Answer:
The principal will need 26.24 m² of plastic to cover the sand pit.
Explanation:
In order to calculate the amount of plastic, we need to find out the area of the sandpit. The shape of the sandpit is a rectangle, so we can use the formula:
A=W×H
where,
W is the width of the sandpit
L is the length of the sandpit
Therefore,
A=2.75 m × 9.54 m = 26.24 m²
The amount of plastic needed is 26.24 m²
