If each side of a square increases by 20%, then the area of the square will increase by 44%.
To see why, consider a square with sides of length 1. If each side is increased by 20%, then each side becomes 1.2. The new square has sides of length 1.2, so its area is 1.2 * 1.2 = 1.44, which is a 44% increase from the original area of 1.
