Question

The triangular side walls of a flyover have been used for advertisements. The sides of the walls are 122 m, 22 m and 120 m. The advertisements yield an earning of Rs. 5000 per m² per year. A company hired one of its walls for 3 months. How much rent did it pay?

Answer 1

Sides of triangle, a = 122m, b = 22m, c = 120m.

Rent for each year, each sq.m. = Rs. 5,000 

Rent for each month, each sq.m. = \(\frac{5000}{12}\)

Rent for each quarterly, each sq.m. = 3 × \(\frac{5000}{12}\) = Rs. 1250 

∴ Rent for 1320 sq.m.= 1250 × 1320 = Rs. 1650000 

∴ Amount company has to pay is Rs. 1650000.
