a person has a rectangular garden one length of the garden lies along the patio wall. however the rest of the garden is enclosed by 30 ft of fencing. if the length of the garden is three times its width, what is the area of the garden

Answer 1

L = 3W

L + 2W = 30

Substitute 3W for L in the second equation and solve for W. Insert that value into the first equation to solve for L. Check by putting both values into the second equation.

Area = L * W
