Team Careers360 · Accepted Answer

Correct Answer: INR 1,712

Solution : Length = 7 m, Breadth = 5 m, Height = 3 m
Area of four walls = $ ext{2(length +breadth) × height}$
= 2(7 + 5) × 3
= 2 × 12 × 3
= 72 m$^2$
Area of ceiling = $ ext{length × breadth}$ = 7 × 5 = 35 m$^2$
Total area of four walls and ceiling = 72 + 35 = 107 m$^2$
Cost of whitewash = 107 × 16 = 1712
Hence, the correct answer is INR 1,712.
