# Find the co

Given: Sides of a triangle are 70 cm, 50 cm, and 60 cm

Cost of leveling the ground: Rs. 7 per square metre

To Find: The cost of leveling the ground.

Concept Used:

If sides of a triangle are a, b, and c, then area of a triangle is given by: Where s = semiperimeter of the triangle Assumption: Let the sides of triangle be,

a = 70 cm

b = 50 cm

c = 60 cm

Explanation:  s = 90 cm   Area = 600√6 cm2.

1m2 = 104 cm2

600√6 cm2 Cost of leveling of 1 m2 = Rs. 7

Cost of leveling of Hence, the cost of leveling of the ground is Re. 1.
