Answer:

( 3^(4/7) ) square inches

Step-by-step explanation:

So you say that the length of each side of this square is 3^(2/7) inches.  What's the area of the square?  Use the formula A = s^2, which applies to squares of side length s.

Then, in this case, A = ( 3^(2/7) ^2.  This simplifies to A = ( 3^(4/7) ) square inches (Answer B)
