Answer 1

Answer:

Rs. 873

Step-by-step explanation:

Area of walls (including windows and doors) = 2(l + b)h = 2(12 + 6)4.5 sq. m = 9 × 18 sq. m = 162 sq. m

Now, area of doors = 2 × 2.5 × 1.5 sq. m = 7.5 sq. m

Area of windows = 4 × 1.5 × 1.5 sq. m = 9 sq. m

Area of walls that will be whitewashed = 162 - (9 + 7.5) sq. m = 145.5 sq. m

Cost of Whitewashing = Rs. 6 × 145.5 = Rs. 873
