Answer 2

Answer :-

Length = 8m

Breadth = 6m

Height = 7m

Length Of door = 5m

breadth of door = 4m

2 windows length = 4m

2 windows breadth = 1m

4 walls to be painted internally with the rate of 20 sq.m

_____________________

Area of 4 walls = 2 (l+b) h

2 (8+6) 7

2 (14) 7

196

Area = 196 m²

_______________________

Area of door = L x B

5 X 4

20

Area = 20 m²

_______________________

Area of 2 windows = L x B

8 X 1

8

Area = 8 m²

_______________________

Total area painted = area of walls - (area of door + area of windows)

196 - (20+8)

196 - (28)

196-28

168

area painted = 168 m²

Rate of painting bungalow = Rs 20

168 x 20

3360

Rs 3360
