PLEASE MARK IT AS BRAINLIEST.

Solution:

Given;

Length of wall (l)= 15 m,

Breadth of wall  (b)= 10 m Height of wall (h) = 7 m

Total area to be painted= area of 4 walls + area of ceiling

= 2(l+b)h + lb

= 2(15+10)7 + 15×10

= 2×25×7+ 150

=50× 7+150= 350+ 150=500

Total area to be painted=500m²

Given 100m² area can be painted from each can.

 Number of cans Required=

Area of hall/ area of 1 can

= 500/100= 5

Hence, 5 cans are required to paint the room.

Hope this will help you.
