Calculate the total length of wire needed to wrap around a square field with an area of 69,696 m² exactly 15 times.

Explanation

Given the area of the square field is 69,696 m², the side length is √69,696 = 264 meters. The perimeter of the square is 4 × 264 = 1,056 meters. Wrapping the wire 15 times requires 1,056 × 15 = 15,840 meters of wire.
