Answer 2

Calculating the Length of the Fence for a Rectangular Schoolyard

To calculate the length of the fence needed for a rectangular schoolyard, we can use the formula:

Perimeter = 2 * (Length + Width)

Given: - Length of the schoolyard = 25 meters - Width of the schoolyard = 18 meters

Calculation

Using the formula, we can calculate the perimeter:

Perimeter = 2 * (25 + 18) Perimeter = 2 * 43 Perimeter = 86 meters

Therefore, the length of the fence needed for the rectangular schoolyard is 86 meters.
