What is the induced emf in a coil with changing magnetic field?

[SavageWarrior]

Homework Statement

A coil is wrapped with 247 turns of wire on the perimeter of a square frame of sides 27.3 cm. Each turn has the same area, equal to that of the frame, and the total resistance of the coil is 2.53. A uniform magnetic field is turnedon perpendicular to the plane of the coil. If the field changes linearly from 0 to 1.11Wb/m2 in a time of 0.822 s, find the magnitude of the induced emf in the coil while the field is changing.
Answer in units of V.​

Homework Equations

flux = B*a*cos(theta)
E = -N (flux/t)

The Attempt at a Solution

flux = (1.11)(745.29)(1/10000) = .074529
E = (247)(.074529)/(.822) = 22.395
Just not sure if it is right or not
