The Brainliest Answer!

b = 6.5 m

h = 3.4 m

length = 1.5 m

b = 1 m

length = 2 m

b = 1 m

Area Wall-Area Door - Area Windows = Area of painting

4*6.5*3.4 - 2*1.5*1 - 2*2*1 = Area Painting

⇒ 13*6.8 - 3 - 4

⇒ 88.4 -7

⇒81.4 m² is the area of painting the walls.

Cost of painting 1 m² = Rs. 160

Cost of painting 81.4 m² = Rs. 81.4*160

⇒ Cost of Painting the walls is Rs. 13024.
