Electro Magnetic Induction: EMF induced due to shape change

An emf is induced in a conducting loop of wire 1.24 m long as its shape is changed from square to circular. Calculate the average magnitude of the induced emf if the change in shape occurs in 4.03s, and the local 0.109 T magnetic field is perpendicular to the plane of the loop.

Please solve and explain problem.
