The side of a square is 2 and 7/2 inches. use the area formula a=s2 to determine the area of the square. 1. a= 196 square inches 2. a= 128 square inches 3. a= 49 square inches 4. a= 4 square inches *will give brainleist answer*

2 to the power of (7/2) can be written as sqrt (2^7), since the 2 on the bottom of the exponent can be turned into a root.

Then, since sqrt (2^7) is the side length, we square it to get the area. If you square a square root, they cancel out, so you are left with 2^7 = 128 inches squared.

The answer is choice (B).
