Rectangles don't have depth. If your figure has three dimensions, divide the area by the product of the two dimensions you know. The quotient will be the third dimension.
You must use the information given that describes that particular rectangle,together with the laws, equations, and formulas you have that relate to theproperties of rectangles, to derive the missing information.The answer will depend on what dimension is missing and what information you do have.
It is a 3 x 15 rectangle !
The diagonal is 47.707'
The diagonal is 100'
8.125 inches
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.
I can give the width of one of the rectangles. The first rectangle of area 15 cm2 and length of 5 cm has width of 3 cm. It is impossible to know the width of the other rectangle of area 60 cm2. However, if you had said that the two rectangles were similar, then the dimensions of the second rectangle would be 10 cm X 6 cm. But you didn't say that the two rectangles were similar; so there are infinite possibilities of what the dimensions of the second rectangle might be.
The dimensions work out as length = 9 and width = 5
There are infinitely many of them. Any rectangle with dimensions 2*a where a > 22 cannot b made. So, 2*23, 2*24, 2*25, and so on.
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.
A square is a rectangle, rectangles don't have to be squares but squares have to be rectangles.
