The question cannot be answered because the units for 15 * 15 are not known. 15mm * 15 mm? 15 miles * 15 miles? or 15 light years * 15 light years.
Even if they were, it would not be possible to give a sensible answer to the question. 15*15 is a measure of area, with dimensions [L2]. An inch is a measure of distance, with dimensions [L]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
A "something" with the dimensions of 15x15 inches has an area of 225 square inches. Since the sides are the same, this "something" can be considered as a square.

A square has four equal sides. If its perimeter is 60 inches, then each side is 15 inches. A 15x15 square has an area of 15x15 = 225 square inches.
