A path is 60m long and 1.2m wide this path is required to lay by rectangular stones which are 12cm long and 7.5 cm broad find the number of stones required to lay the path
Ap/As = (6000cm * 120cm)/(12*7.5) = 8000 stones.

To find the number of stones required to lay the path, we need to calculate the area of the path and divide it by the area of each stone.
Step 1: Convert the measurements to the same unit.
- The length of the path is 60m, and the width is 1.2m.
- Convert the length of the path to centimeters: 60m * 100 cm/m = 6000cm.
- The width of the path remains the same at 1.2m.
Step 2: Calculate the area of the path.
- Area = length * width
- Area = 6000cm * 1.2m = 7200cm².
Step 3: Calculate the area of each stone.
- Length of the stone is given as 12cm.
- Width of the stone is given as 7.5cm.
- Area of each stone = length * width
- Area of each stone = 12cm * 7.5cm = 90cm².
Step 4: Divide the area of the path by the area of each stone.
- Number of stones = Area of path / Area of each stone
- Number of stones = 7200cm² / 90cm² = 80.
Therefore, you will need 80 rectangular stones to lay the path.
To find the number of stones required to lay the path, we need to calculate the area of the path and then divide it by the area of each stone.
First, let's convert the dimensions of the path from meters to centimeters:
Length of the path = 60m = 60 * 100 cm = 6000 cm
Width of the path = 1.2m = 1.2 * 100 cm = 120 cm
Now we can calculate the area of the path:
Area of the path = Length * Width = 6000 cm * 120 cm = 720,000 cm²
Next, let's calculate the area of each stone:
Length of the stone = 12 cm
Width of the stone = 7.5 cm
Area of each stone = Length * Width = 12 cm * 7.5 cm = 90 cm²
Finally, we can find the number of stones required by dividing the area of the path by the area of each stone:
Number of stones = Area of the path / Area of each stone
Number of stones = 720,000 cm² / 90 cm²
Number of stones = 8,000 stones
Therefore, you would need 8,000 stones to lay the path.
