Question

The length of a rectangle is 3 feet less than twice the width of the rectangle. if the perimeter of the rectangle is 204 feet, find the width and the length.

Answer 1

Let the width be x
width = x
length = 2x - 3
Perimeter = Length + Length + Width + Width
Perimeter = 2x -3 + 2x - 3 + x + x = 6x - 6
Given that the perimeter is 204
6x - 6 = 204
6x = 204 + 6
6x = 210
x = 35 feet
2x - 3 = 2(35) - 3 = 67 feet
Length = 67, Width = 35
