Question

a hall is 25 m long 20 broad and 5 metre find the cost of the painting four walls and ceiling and Rupees 15 per metre​

Answer 1

Answer:

Length = 25m

Breadth = 20 m

Height = 5m

The curved surface area of 4 walls 2 (l + b ) x h

= 2 (20+25) x 5

= 450 m^2

Ceiling

= l x b

=20 x 25

= 500 m^2

Curved Surface area + Ceiling

450m^2 + 500^2

= 950 m^2
