A wire 10 cm long is cut into two pieces, one of length x and the other of length
10 − x,
as shown in the figure. Each piece is bent into the shape of a square.

(a) Find a function that models the total area enclosed by the two squares. (Let x be the length of wire in cm that is bent into a square and A(x) be the area.)

(b) Find the value of x that minimizes the total area of the two squares.
