An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 390 feet of antiqu
e picket fencing are to be used to enclose the garden, find the dimensions of the garden.
1 answer:
Length (L): L
width (w): (2/3)L
Perimeter (P) = 2L + 2w
390 = 2(L) + 2(2/3)(L)
1170 = 6L + 4L
1170 = 10L
117 = L
width (w): (2/3)L = (2/3)(117) = 2(39) = 78
Answer: width = 78 ft, length = 117 ft
