Answer provided by our tutors
We will assume that the garden is rectangular. Let
l = the length of the garden, l>0
w = the width of the garden, w>0
A = 120 ft^2 the area of the garden
The garden is 12 ft longer than it is wide:
l = 12 + w
The area of a rectangle is:
A = l*w
l*w = 120 plug l = 12 + w into the last equation:
(12 + w)*w = 120
........
........
w = 6.49 ft
l = 12 + 6.49
l = 18.49 ft
The vegetable garden should be 6.49 ft wide and 18.49 ft long.
