Why it is possible for rectangles to have the same perimeters but different areas?

This is possible because you add perimiters but multiply areas. Consider a 2 x 4 rectangle and a 1 x 5 rectangle. The first has a perimeter of 12 (2+2+4+4), and an area of 8 (2 x 4). The second rectangle has a perimeter of 12 also (1+1+5+5), but an area of 5 (5 x 1). The closer a rectangle is to a perfect square, the larger the area will be, because a square maximizes area. A 3 x 3 square also has a perimeter of 12, but an area of 9. Heres another way to think about it: a rectangle that is one inch tall and 100 inches wide would have a perimeter of 202 inches, and an area of 100 square inches. If you added one inch to the side so that it was 101 inches wide, you would add 2 inches to the perimeter, but only one square inch to the area. However, if you made it one inch taller, you would still add 2 inches to the perimeter, but you would DOUBLE the area to 200 square inches.

How many feet is it around 100 acres?
You can't tell the shape or the distance around from the area. There are an infinite number of shapes and perimeters that all have areas of 100 acres. The shortest perimeter possible is a circle, with diameter (distance across) of 2,355 feet. The distance around it is 7,398 feet (about 1.4 miles). The shortest possible perimeter with straight sides is a square, 2,087 feet on every side. The distance around it is 8,348 feet (about 1.58 miles). If you stay with rectangles, there are an infinite number of different rectangles with different dimensions and different perimeters, that all have areas of 100 acres. The distance around every one of them is larger than 1.58 miles, and it can be anything up to infinity.
How are rectangles related to the distributive property?
Rectangles are related to the distributive property because you can divide a rectangle into smaller rectangles. The sum of the areas of the smaller rectangles will equal the area of the larger rectangle.
Can rectangles with the same perimeter have different areas?
Yes. Say there are two rectangles, both with perimeter of 20. One of the rectangles is a 2 by 8 rectangle. The area of this rectangle is 2 x 8 which is 16. The other rectangle is a 4 by 6 rectangle. It has an area of 4 x 6 which is 24.
What is the side length of an area of 9 square meter?
If it's a square, then each side is 3 meters long.But there are an infinite number of different rectangles, with all differentlengths and widths, that all have areas of 9 square meters.
Two rectangles have a perimeter of 16 inches Name two possible areas for each rectangle?
* It is unclear if the question is asking about two rectangles, each with a perimeter of 16, or two rectangles whose perimeters sum to 16. This answer assumes the former.Other than the 4x4 square, which coincidentally has both a perimeter and area of 16, some examples would be:1 x 7 rectangle : perimeter 16 in. , area 7 sq. in2 x 6 rectangle : perimeter 16 in., area 12 sq. in3 x 5 rectangle: perimeter 16 in., area 15 sq. inYou can calculate that for a given perimeter, the largest area is found in the square with a side measurement of P/4, i.e. the length and the width are the same.
Is it true that the greater the perimeter the greater the area?
No, in general that is not true. For two similar figures it is true. But you can easily design two different figures that have the same perimeters and different areas, or the same area and different perimeters. For example, two rectangles with a different length-to-width ratio.
What is the relationship for perimeter and area for rectangle?
There is no relationship between the perimeter and area of a rectangle. Knowing the perimeter, it's not possible to find the area. If you pick a number for the perimeter, there are an infinite number of rectangles with different areas that all have that perimeter. Knowing the area, it's not possible to find the perimeter. If you pick a number for the area, there are an infinite number of rectangles with different perimeters that all have that area.
What is the width of two similar rectangles are 45 yd and 35 yd what is the ratio of the perimeters of the areas?
The ratio of their perimeters is also 45/35 = 9/7. The ratio of their areas is (9/7)2 = 81/63
What do you know about the perimeters of similar figures?
The areas are different.
Why would two shapes have equal areas and perimeters?
There is no particular reason. In fact, in general, two shapes will have different areas or perimeters or both.
Can a parallelogram and a rectangle have the same perimeters but different areas?
Yes.
Do these rectangles have the same perimeter 12 meters x 4 meters and 13 meters x 3 meters?
Yes they do. Both perimeters are 32 meters. But notice that they have different areas: 48 m2 and 39 m2 .
Can different rectangles have the same area and perimeter?
It's very easy for two rectangles to have the same area and different perimeters,or the same perimeter and different areas. In either case, it would be obvious toyou when you see them that there's something different about them, and theywould not fit one on top of the other.But if two rectangles have the same area and the same perimeter, then to look at themyou'd swear that they're the same rectangle, and one could be laid down on the otherand fit exactly.
How many feet is it around 100 acres?
You can't tell the shape or the distance around from the area. There are an infinite number of shapes and perimeters that all have areas of 100 acres. The shortest perimeter possible is a circle, with diameter (distance across) of 2,355 feet. The distance around it is 7,398 feet (about 1.4 miles). The shortest possible perimeter with straight sides is a square, 2,087 feet on every side. The distance around it is 8,348 feet (about 1.58 miles). If you stay with rectangles, there are an infinite number of different rectangles with different dimensions and different perimeters, that all have areas of 100 acres. The distance around every one of them is larger than 1.58 miles, and it can be anything up to infinity.
How many rectangles have the same area but different perimeters?
Infinitely many. Suppose the area of the rectangle is 100. We could create rectangles of different areas: 100x1 50x2 25x4 20x5 10x10 However, the side lengths need not be integers, which is why we can create infinitely many rectangles. Generally, if A is the area of the rectangle, and L, L/A are its dimensions, then the amount 2(L + (L/A)) can range from a given amount (min. occurs at L = sqrt(A), perimeter = 4sqrt(A)) to infinity.
What is the area of a rectangle that its perimeter is 56 centimeters?
You can't tell. The perimeter doesn't tell you the area. There are an infinitenumber of different rectangles, with different dimensions and different areas,that all have perimeters of 56.The greatest area it can have is 196 cm2 ... if it's a square with 14-cm sides.If it's not a square, then it can have any area less than 196 cm2.Here are a few rectangles. They all have perimeters of 56:1 x 27, area = 272 x 26, area = 523 x 25, area = 754 x 24, area = 965 x 23, area = 11510 x 18, area = 18013 x 15, area = 195
Two triangles are similar and have a ratio of similarity of 3 1 What is the ratio of their perimeters and the ratio of their areas?
The ratio of their perimeters will be 3:1, while the ratio of their areas will be 9:1 (i.e. 32:1)
