Cost of Cementing the Verandah Floor

To calculate the cost of cementing the floor of the verandah, we need to determine the area of the verandah and then multiply it by the cost of cement per square meter.

Step 1: Calculate the Area of the Verandah

The verandah surrounds the room and has a width of 1.25 m. We can calculate the area of the verandah by subtracting the area of the room from the area of the verandah along with the room.

Area of the room = Length × Width = 9.5 m × 6 m = 57 square meters

Total length of the verandah along with the room = Length of the room + 2 × Width of the verandah
= 9.5 m + 2 × 1.25 m = 9.5 m + 2.5 m = 12 m

Area of the verandah = Total length of the verandah along with the room × Width of the verandah
= 12 m × 1.25 m = 15 square meters

Step 2: Calculate the Cost of Cementing

The cost of cementing per square meter is given as 80 per m². We can now calculate the cost of cementing the verandah floor by multiplying the area of the verandah by the cost per square meter.

Cost of cementing the verandah floor = Area of the verandah × Cost per square meter
= 15 m² × 80 = 1200

Therefore, the cost of cementing the verandah floor is 1200.

Conclusion

To calculate the cost of cementing the verandah floor, we first determined the area of the verandah by subtracting the area of the room from the total area of the verandah along with the room. Then, we multiplied the area of the verandah by the cost per square meter to obtain the final cost. In this case, the cost of cementing the verandah floor is 1200.
