What are all the possible dimensions of a rectangle that has a perimeter of 18 cm?
If you are looking for dimension in whole numbers only, and understanding that rectangles must have opposing sides equal and 4 right angles:
The answer to your question is most easily determined by assigning the dimension of 1cm (the smallest possible whole unit) to two of the sides. This means that the other two sides must each be 8cm. Because 18-1-1=16. 16/2 = 8. So the dimensions of the first rectangle would be 1cmX8cm. If the next rectangle were assigned a dimension of 2cm to two of the sides, the longer sides would each be 7cm. Because 18cm-2-2=14. And 14/2=7. If the next rectangle had short sides of 3cm, it would have long sides of 6cm. So you see, for every 1cm that the short sides are increased, the long side must be decreased by 1cm.
So the dimensions would look like this:
1x8
2x7
3x6
4x5
at this point the lengths of the sides invert
5x4
6x3
7x2
8x1
It could be said that there are 4 possible sizes of a rectangle (in whole numbers), or it could be said that there are 8 if you consider the inverse dimensions to differ because they refer to different sides.

What is a perimeter of a recangular?
Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
How do you get a permeter of 14 with 6 as the area?
To find the perimeter of a rectangle with a given area, you need to know the dimensions of the rectangle. In this case, the area is 6, so the possible dimensions could be 1 x 6 or 2 x 3. For a perimeter of 14, the dimensions would need to be 2 x 5, as (2 + 2) + (5 + 5) = 4 + 10 = 14.
The length of a rectangle is 13.6cm the perimeter of the rectangle is 37.8cm what is the width?
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
What is the perimeter of a rectangle 7 inches by 8 inches?
The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.
How is perimeter and area related in a rectangle?
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
All possible whole number dimensions for rectangle with perimeter of 10 units?
If the dimensions are restricted to whole numbers, then the only possibilities are 1 x 4 and 2 x 3.
What are all the possible whole number dimensions for a rectangle having a perimeter of 20?
1 x 20 2 x 10 4 x 5
How do you find the dimensions of a rectangle with only the area and perimeter?
There are often multiple 'correct' dimensions for these problems. The most straight forward way to solve it is to list all the factors that, when multiplied, equal the area. Then from this list, cross out the factors that DON'T equal your perimeter. The remaining factors are your possible dimensions.
What is the length of the sides of a rectangle that has a perimeter of .875?
You can't tell the dimensions from the perimeter. There are an infinite number of different rectangles, all with different lengths and widths, that all have the same perimeter.
Does the perimeter of a rectangle change when you double the dimensions?
Yes. The perimeter is a measure of the combined length of all the sides. If you double the lengths of the sides then naturally this will also necessarilychange the perimeter (it will double the perimeter).
How do you determine the area of a rectangle if you know the perimeter?
You can't. The perimeter doesn't tell the area. There are an infinite number of shapes with different dimensions and different areas that all have the same perimeter.
Is the area the same on all rectangles with the same perimeter?
No, it is not. I'll give you two examples of a rectangle with a perimeter of 1. The first rectangle has dimensions of 1/4x1/4. The area is 1/16. The second rectangle has dimensions of 3/8x1/8. The area is 3/64. You can clearly see that these two rectangles have the same perimeter, yet the area is different.
How do you calculate the dimensions of a rectangle if you know the perimeter and the length?
A rectangle by definition has two pairs of sides with equal length. Since perimeter equals the length of all the sides. The equation for the perimeter of a rectangle could be thought of as: 2L + 2W = P Where L represents the length of one side of the rectangle and W represents the length of the adjacent (next to) side of the rectangle. If you know the length of one side and the perimeter, plug those values in as L and P and then solve for W. That will give you L and W which are the dimensions of the rectangle.
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 perimeter of 1437 square meters?
The area doesn't tell you the dimensions or the perimeter. It doesn't even tell you the shape. The shortest perimeter that could enclose that area would be a circle. The shortest perimeter with straight sides would be a square. If it's a rectangle, then there are an infinite number of them, all with different dimensions and different perimeters, that all have the same area.
If The area of a rectangle is 176 sq cm what is the perimeter?
You can't tell the perimeter from knowing the area.There are an infinite number of rectangles with different dimensions that all have the same area.Here are a few examples.1 x 176 . . . perimeter = 3542 x 88 . . . perimeter = 1804 x 44 . . . perimeter = 968 x 22 . . . perimeter = 6016 x 11 . . . perimeter = 5413.266 x 13.266 . . . perimeter = 53.066All of these have an area of 176, but they all have different perimeters.The last one on the list is a square. That's the rectangle with the shortest possible perimeterthat has the area you want.The perimeter of this square is 53.066. You can make a rectangle with any perimetermore than that, and an area of 176.
What is the perimeter of a rectangle that has an area of 432 feet?
Ah, what a lovely question! To find the perimeter of a rectangle, we need to know both the length and width. Since the area is 432 square feet, we can find the dimensions by factoring 432 into pairs of numbers until we find a pair that could be the length and width of the rectangle. Once we have the dimensions, we can simply add up all the sides to find the perimeter.
