Question 445888: A farmer wishes to enclose a rectangular pasture which borders are river. the pasture is to have a length parallel to the river equal to twice the width, no fencing is needed along the side which borders the river, and the enclosed area is to be 39,200 yd^2. How many yards of fence is needed?
Answer by cleomenius(959) (Show Source): You can put this solution on YOUR website!
First, set up an equation to find the values for the length and width.
(x)* (2x) = 39200
2x^2 = 39000
x^2 = 19,600
x = 140.
The length is 280 yd.
The width is 140 yd.
So we need a length of 280 yards parallel to the river, and we need two sections of 140 for the width of the pasture.
Total, our farmer is going to need 560 square yards of fencing.
