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

The perimeter P of the rectangular pasture of sides x and y is:
P=2x+2y=160 ft
if x=50 ft then y=(160-100)/2=30 ft
Area A=x*y=50*30=1500 ft^2
