Question 1084566: he area of a rectangular wall of a barn is 9696 square feet. Its length is 44 feet longer than twice its width. Find the length and width of the wall of the barn.
You can put this solution on YOUR website! Let w be the width of the wall. Then its length is 2w+44. So:
w(2w+44)=9696
2w²+44w-9696=0
w²+22w-4848=0
Using the quadratic formula, we get a positive root of 59.4911341943 ft. for the width, which gives us 162.982268389 ft. as its length. ☺☺☺☺
