If you have 36ft. of fencing what are the areas of the different rectangles you could enclolse with the fencing?

The areas are many. If you have 36 feet of fence you can make a rectangle 8' x 10' x 8' x 10'. That rectangle would be 80 square feet. 8 x 10 = 80 9 x 9 x 9 x 9 would be 81 square feet. 9 x 9 = 81 12 x 6 x 12 x 6 would be 72 square feet. 12 x 6 = 72 3 x 15 x 3 x 15 would be 45 square feet. 3 x 15 = 45 All the sides of each rectangle add up to 36 which is the length of fence that you had. You could make one 1 x 17 x 1 x 17 which would be 17 square feet. 1 x 17 = 17 17 (17x17x1x1) 32 (16x16x2x2) 45 (15x15x3x3) 56 (14x14x4x4) 65 (13x13x5x5) 72 (12x12x6x6) 77 (11x11x7x7) 80 (10x10x8x8) 81 (9x9x9x9) [a square is, in a way, a rectangle that's gotten its act together]

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.
What is the area of a L shaped room?
An L-shaped area can be divided into two rectangles. The total area is the sum of the areas of the two rectangles.
What is the perimeter of 5000 acres in meters?
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area. Even if you consider only rectangles, there are still an infinite number of different rectangles, all with different lengths and widths, that all have areas of 5,000 acres.
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
Rectangles with the area of 24cm?
In order to get a rectangle with an area of 24 centimeters, the length and width multiplied need to equal 24. On top of that, length and width may not be equal, or the shape would be a square instead of a rectangle. Examples of rectangles with 24cm areas: 1x24 cm 2x12 cm 3x8 cm 4x6 cm
Why could two students obtain different values for the calculated areas of the same rectangle?
because it was estimation, the lengths were different and the rectangles are not the same
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.
How do you find the areas of the rectangles?
multiply the length with the breadth.
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.
When you use the Distributive Property to find areas of rectangles why does it make sense to divide the rectangles so you get groups of 10?

How are the areas of similar rectangles related to the scale factor?
The areas are proportional to the square of the scale factor.
Find 4 rectangles with same area with different perimeter?
10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2

How do you figure area when all 4 sides are different?
You need to cut up your figure into several parts in shapes for which we know how to calculate areas, such as squares, rectangles, and triangles. The area of your figure is the sum of the areas of its parts.
What is the perimeter of 5000 acres in meters?
You can't tell the linear dimensions from knowing only the area. There are an infinite number of shapes that all have the same area.

What strategies are there to find the surface area of three-dimensional shapes made from rectangles and triangles?
Find the areas of the rectangles and triangles. Add them together.
