Question

I need to know how long is each side of the infield. Btw in the picture on the bottom right it says A=81in squared

Answer 1

The infield of a baseball stadium is diamond shaped, which means each side is the same length.

If the whole area of the diamond is 81 inches, then each side has to be 9 inches.

A = b²
81 = b²
√81 = b
9 = b
