A wire L = 28 cm long is cut into two pieces, one of length x and the other of length L − 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 A enclosed by the two squares in terms of x.(b) Find the value of x that minimizes the total area of the two squares.
