Question

Find the cost of painting the walls of a room if the room is 4 m 50 cm high and each side of
the room is 6 m long. The cost of painting is Rs 10 per sq m.
​

Answer 1

Answer:

Firstly we have to find it's CSA

CSA= 2h(I+b)

= 2×4.50(6+6)

= 9×12

= 108m²

if 1m²= rs 10

Then 108m²= rs 1080
