Answer:

Rs. 16,50,000

Explanation

Let the sides of the triangular will be

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22m

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c(122+120+224)m = 2642 m = 132m

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c(122+120+224)m = 2642 m = 132mThe area of the triangular side wall

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c(122+120+224)m = 2642 m = 132mThe area of the triangular side wallRent for 1 year (i.e. 12 months) per m2 = Rs. 5000

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c(122+120+224)m = 2642 m = 132mThe area of the triangular side wallRent for 1 year (i.e. 12 months) per m2 = Rs. 5000∴ Rent for 3 months per m2 = Rs. 5000 x 312

Let the sides of the triangular will bea = 122m, b = 12cm, c = 22mSemi-perimeter, s = a+b+c(122+120+224)m = 2642 m = 132mThe area of the triangular side wallRent for 1 year (i.e. 12 months) per m2 = Rs. 5000∴ Rent for 3 months per m2 = Rs. 5000 x 312= Rent for 3 months for 1320 m2 = Rs. 5000 x 312 x 1320 = Rs. 16,50,000
