Answer:
36 bricks
Explanation:
We are given;
- Length of the square path as 18 cm
- Length of the square brick as 3 cm
We are required to determine the number of bricks that would be laid on the square path.
Number of bricks = Area of the path ÷ area of one brick
Area of a square = l²
Therefore;
Area of the square path = (18 cm)²
= 324 cm²
Area of square brick = (3 cm)²
= 9 cm²
Therefore;
Number of bricks = 324 cm² ÷ 9 cm²
= 36 bricks
