Question

Maria needs to determine the lengths of the sides of a rectangle. She knows only the perimeter of the rectangle. She knows the formula for perimeter is 2l + 2w = P. Which shows how Maria can rewrite the equation to help her find possible lengths and widths for any rectangle?

Answer 1

2L + 2W = perimeter
dividing both sides by 2
L + W = (perimeter / 2)
Length = (perimeter / 2) -Width
Width = (perimeter / 2) -Length
