Question

A farmer builds a fence to enclose a rectangular pasture. He uses 160 feet of fence. Find the total area of the pasture if it is 50 feet long

Answer 1

P = 2(L + W)
160 = 2(50 + W)
160 = 100 + 2W
160 - 100 = 2W
60 = 2W
60/2 = W
30 = W

so length is 50 and width is 30

A = LW
A = (50)(30)
A = 1500 ft^2 <===
