Question

the rectangular garden is 8 feet less then twice the length. Find the dimensions if the perimeter is 20m feet

Answer 1

I'm going to assume you mean the rectangular garden width is 8 feet less than twice the length:

W = 2L-8

2W+2L = 20

2(2L-8) + 2L = 20

4L - 16 + 2L = 20

6L = 36

L = 6

W = 2L-8

W = 2(6)-8

W = 12-8

W = 4

Therefore, the dimensions of the rectangular garden are 6ft x 4ft.

Hope this helped!
