Question

The length of a rectangular garden is three feet less than twice it’s width. If the perimeter of the garden is 42 feet, what is the length?

Answer 1

The length of a rectangular garden is: 13 feet

Explanation:

You have 2 lengths that are 2x-3 feet, and 2 widths that are x.

2x-3 + 2x-3 +x +x =42 feet

4x -6 +2x -42 feet

6x -6 = 42 feet

6x = 48 feet

x = 8 feet (so, 2x-3 = 16-3 = 13 feet)
