Question 288691: Barbie and Ken planned to build a square house that was x feet on each side. Then they revised the plan so that one side was lengthened by 20 feet and the other side was shortened by 6 feet. Find a polynomial function A(x) that gives the are of the revised house in square feet. Answer by texttutoring(324) (Show Source):
You can put this solution on YOUR website! Originally, each side had a length of x.
After the changes, we now have length=l=x+20, and width=w=x-6
The area of a rectangle is just A=l*w
