How many paving stones, each measuring 80cm by 50cm are required to pavea rectangular courtyard 30m long and 20m broad??
Please put the school subject name in the "School Subject" box.
Thank you.
Divide the area of the courtyard (600 m^2) by the area of a paving stone (0.2 m^2).
In practice, a few extras should be included because some pavers may have to be sawed to fill gaps at the edges. There may also be some breakage.
To find out how many paving stones are required to pave a rectangular courtyard, we need to calculate the area of the courtyard and divide it by the area of each paving stone.
Step 1: Calculate the area of the courtyard in square meters.
The length of the courtyard is 30m, and the width is 20m. Therefore, the area of the courtyard is 30m * 20m = 600 square meters.
Step 2: Calculate the area of each paving stone in square meters.
Each paving stone measures 80cm * 50cm. We need to convert these measurements to meters to ensure consistency. Since 1m = 100cm, the dimensions of each paving stone are 0.8m * 0.5m = 0.4 square meters.
Step 3: Divide the area of the courtyard by the area of each paving stone.
600 square meters / 0.4 square meters (area of each paving stone) = 1500 paving stones
Therefore, you will need 1500 paving stones, each measuring 80cm by 50cm, to pave the rectangular courtyard.
