The area of a rectangle is calculated as length x width.
The area of a square is calculated as side x side.
Applying the relevant formula to the current problem:
The area of the basketball court is 40m x 30m = 1,200 square meters.
The area of each tile is 4m x 4m = 16 square meters.
To find out how many tiles is required to cover the basketball court floor, we need to divide the floor area by the tile area. So:
1,200 square meters ÷ 16 square meters = 75
75 tiles are required to cover the basketball court floor.
