Problema Solution
A rancher wants to use 400 feet of fencing to enclose a rectangular area of 3600 square feet. what dimensions should the rectangle have?
Answer provided by our tutors
area = length * width
let 'x' represent the length, then '(400-2x)/2' represents the width
3600 = (x)((400-2x)/2)
------------------
------------------
x={180,20}
So the two dimensions are {20, 180}, a length of 180 feet and a width of 20 feet.
