Find the area in terms of X

Question

A rectangular pen has an area of 340 feet. If x represents its width, wrote a polynomial that gives the area of the pen in terms of x. Show your work.

Answer 1

A(x) = WL = xL

where x= width and L= Length

A(x) = xL =340

A(x) = x(340/x) = 340

Answer 2

A(x) = x(340 - x)
