What dimensions on a rectangles have a perimeter of 120?

Answer 1

Not enough information. This means that there are many solutions.

Therefore, the most complete way to give an answer is in the form of a formula.

Set the definition of W and L to:

W = width of rectangle

L = length of rectangle

2W + 2L = 120 [Perimeter of 120 = (Length*2) + (Width*2)]

Which simplifies to

{W = 60-L | 0 < L <60}

(values for X and Y have to be between 0 and 60, but not exactly 0 or 60)

So replace L (length) in the simplified formula with any number that is between 0 and 60. Subtract this number from 60 to determine the corresponding width.

For example, I can replace L with 40, and the equation becomes

W = 60-40

Simplifies to

W = 20

So, one possible solution is W=20 and L=40.
