the garden is 42 feet

Question

the perimeter of a rectangular garden is 42feet. the length of the garden is 6 feet less than twice the width. the the dimensions of the garden.

Answer 1

Let w = the width

Let 2w - 6 = the length

P = 2l + 2w

42 = 2(2w - 6) + 2w

42 = 4w - 12 + 2w

54 = 6w

9 feet = w

2w - 6 = 2(9) - 6 = 18 - 6

length = 12 feet
