Answer 2

Calculation of the Perimeter of the Schoolyard

To find the perimeter of a rectangular schoolyard, we need to add up the lengths of all four sides. Given that the length of the schoolyard is 300 meters and the width is 200 meters, we can calculate the perimeter as follows:

Perimeter = 2 * (Length + Width)

Substituting the given values:

Perimeter = 2 * (300 + 200) = 2 * 500 = 1000 meters

Therefore, the perimeter of the schoolyard is 1000 meters.

Calculation of the Number of Chairs in the Hall
