Answers
Answer:
Rs 10,600
Step-by-step explanation:
Find the area of the 4 walls:
Area = Perimeter x height
Area = 2(9 + 8) x 6.5 = 221 m²
Find the area of the windows and door:
Door = 2 x 1.5 = 3 m²
Windows = 4( 1.5 x 1) = 6 m²
Total = 3 + 6 = 9 m²
Find the area of the wall without door and windows:
Area = 221 - 9 = 212 m²
Find the cost:
1 m² = Rs 50
212 m² = 50 x 212 = Rs 10,600
