For ceiling

the area of ceiling is = 12 × 10 = 120ft²

white paint cost = 120ft²

Now the four walls cost

  • area of two walls which doesn't have windows and door.

area of two wall = 2×{length × width}

= 2(8×10)

=2×80

=160ft²

  • area of two walls which have 2 windows and door.

for calculating this we need to subtract that area of 2 windows and door from the total area of door.

total area of two walls was 160ft²

area of door is 22sq²

area of two windows= 2 ×(2²) = 8ft

total = 22+8 = 30ft²

Area of two walls which have 2 windows and one door = 160- 30

= 130ft²
