You can put this solution on YOUR website! A piece of wire 16 inches long is to be cut in two parts. Each piece will be bent in the shape of a square. Find the expression that represents the total area of the two squares made with the pieces of wire as a function of the length, x, of one of the pieces.
..
let x=side of first square
let y=side of second square
Total Area = x^2+y^2
Amt of wire used by first square=4x
Amt of wire left for second square=16-4x
Side of second square=y=(16-4x)/4=4-x
Area of second square=16-8x+x^2
Total area=x^2+16-8x+x^2
ans: 2x^2-8x+16
