A wire 10 cm long is cut into two pieces, one of length x and the other of length 10 y- x, as shown in the figure. Each piece is bent into the shape of a square. -10 cm 10 - x (a) Find a function that models the total area enclosed by the two squares. A(X) = (b) Find the value of x that minimizes the total area of the two squares. x = cm
