an architect designs a rectangular garden such that the width is exactly two thirds of the length. If 270 feet of antique picket fencing are to be used to enclose the garden,

Answer 1

W = 2L/3

270 = 2W + 2L

135 = W + L = 2L/3 + L= 5L/3

L = (3/5)135 = 3(27) = 81 feet long

W = (2/3)81 = 54 feet wide

2(81+54) = 270
