The triangular si

Answer :

As shown in the figure the sides of the triangular side walls of flyover are 122 m, 22 m, and 120 m.

Perimeter of the triangle = 122 + 22 + 120 = 264 m

Semi perimeter of triangle(s) =

= 132 m

Now,

Using Heron’s formula

Area of the advertisement =

where, s = semi perimeter of triangle and a, b, and c are the sides of the triangle.

=

=

=

= 132 x 10 m2

= 1320 m2

Rent of advertising per year = Rs. 5000 per m2


Rent of one wall for 1 year = 1320 x 5000

Rent of one wall for 3 months =


Rent of one wall for 3 months = Rs. 1650000
