A play area is in shape of a right triangle. The base is 125 meters and the height is 64 meters. What is the area in the square meters?

The area of a right triangle is given by the formula: 1/2 * base * height

Plugging in the given values:
1/2 * 125 * 64 = 4000 square meters

Therefore, the area of the play area is 4000 square meters.
