Answer 2

The sides of the triangle id 122 m, 22 m and 120 m respectively.

The perimeter will be (122+22+120) = 264 m

The semi perimeter (s) = 264/2 = 132 m

Using Heron’s formula,

Area of the triangle = [s(s-a)(s-b)(s-c)]

= 132(132-122)(132-120)(132-22)

= 1320 m²

Rent of advertising per year = ₹ 5000 per m²

∴ The rent of one wall for 3 months = Rs.(1320×5000×3)/12

=Rs. 1650000
