Answer 1

Answer: cost of cementing = ₹13320

Step-by-step explanation:

Measurement of auditorium + verandah:-

Length = 40 + 4.5 + 4.5 = 49

Breadth = 25 + 4.5 + 4.5 = 34

Area of auditorium + verandah = 49 * 34 = 1666 m²

Area of auditorium = 40 * 25 = 1000 m²

Area of verandah = (area of auditorium + verandah) - (area of auditorium)

=> area of verandah = 1666 - 1000 = 666 m²

1 hectare ——— 10000 m²

666 m² ——— 666 / 10000 = 0.0666 hectares

1 hectare = ₹200000

0.0666 hectares = 0.0666 * 20000 = ₹13320

Cost of cementing = ₹13320
