Suppose a 50-turn coil lies in the plane of the page in a uniform magnetic field

Suppose a 50-turn coil lies in the plane of the page in a uniform magnetic field that is directed into the page. This coil originally has an area of 0.275m2It is squished to have no area in 0.175s.

What is the magnitude of the average induced emf in volts if the uniform magnetic field has a strength of 1.5T?
