Answer:
Step-by-step explanation:
The formula for determining the area of a rectangular playground is expressed as
Area = length × width
The rectangular playground is 40 meters by 10 meters. This means that the area of the playground would be
Area = 40 × 10 = 400 m²
Each bag of the wooden Chips to be used to cover the playground covers 200 sq meters. The number of bags needed would be
400/200 = 2 bags
Each bag costs $30. Therefore, the total cost for this project would be
2 × 30 = $60
