how much rent did a company pay by hiring a triangular side wall of for 4 months whose area is 800 M² the rate of rent is rupees 510 per square m per year for the wall
Answers
Answer:
Given: Dimensions of the triangular sides of walls.
By using Heron’s formula, we can calculate the area of triangle.
Heron's formula for the area of a triangle is: Area = √s(s - a)(s - b)(s - c)
Where a, b and c are the sides of the triangle, and s = Semi-perimeter = Half the Perimeter of the triangle
Triangular sides of walls are, a = 122 m, b = 22 m, c = 120 m
Semi Perimeter, s = (a + b + c)/2
= (122 + 22 + 120)/2
= 264/2
= 132 m
By using Heron’s formula,
Area of a triangle = √s(s - a)(s - b)(s - c)
Substuting the values in order to find area of triangular wall,
= √132(132 - 122) (132 - 22) (132 - 120)
= √132 × 10 × 110 × 12
= 1320 m
Rent of 1 m2 area per year = ₹ 5000
Rent of 1 m2 area per month = ₹ 5000/12
Rent of 1320 m2 area for 3 months = ₹ (5000/12) × 3 × 1320
= ₹ 1650000
Therefore, the company paid ₹ 16,50,000 as rent.
