Question

# The total area of 4 walls of a room is 120 m2 Its height is 2 metres If the floor in the form of a square, find the total cost of flooring at the rate of Rs 78 per m2 and painting the ceiling at the rate of 126 per m_{2</sub}

- Rs 45600
- Rs 45900
- Rs 45700
- Rs 45800

## The correct answer is: Rs 45900

### To find the cost of flooring and painting for the ceiling.

area of 4 walls = 4lh = 120

l= 120/8 = 15 meters

total cost of flooring = 78 x 225

total cost of ceiling = 126 x 225

total cost = flooring + ceiling = 45900 Rs.

Cost of flooring and painting for the ceiling is Rs 45900.
