The sides of the triangle (i.e., a,b,c) are of 122m, 22m, and 120m respectively.
Perimeter of triangle = ( 122+22+120) m
2s = 264m
S = 132m
By Heron’s formula,
Area of triangle = √
Area of given triangle = ⌊√(132−122)(132−22)(132−120)⌋m2=⌊√⌋m2=1320m2
Rent of 1 m2 area per year = Rs 5000
Rent of 1 m2 area per month = Rs.500012
Rent of 1320 m2 area for 3 months = (Rs.500012×3×1320)
Therefore, the company has to pay Rs. 1650000.
