(adsbygoogle = window.adsbygoogle || []).push({}); motional emf i think..... change in area and magnetic field

1. The problem statement, all variables and given/known data

A rectangular loop is located in a uniform magnetic field of magnitude 0.29 T directed perpendicular to the plane of the coil. If the area of the coil increases at the rate of 5.2 10-3 m2/s, what is the magnitude of the emf induced in the coil?

2. Relevant equations

ummmm maybe emf=blv

emf=-L (I/t)

3. The attempt at a solution

honestly i don't even understand conceptually what is going on in this problem so it is hard for me to find any equation(s) to help me solve it. The area of the coil decreases? that doesnt make sense to me and i have no idea what correlation that has to magnetic field other then flux=BA.... so help?
