A fence around a field is shaped as shown in Figure P12. It consists of a rectangle of length L and width W, and a right triangle that is symmetrical about the central horizontal axis of the rectangle. Suppose the width W is known (in meters) and the enclosed area A is known (in square meters). Write a user-defined function le with W and A as inputs. The outputs are the length L required so that the enclosed area is A and the total length of fence required. Test your function for the values W = 6 m and A = 80 m2.
