Question

find the cost of levlling the ground in the form of triangle having the side 26m, 28m, 30mat the rate of ₹3per msquare​

Answer 1

Answer:

₹1008.

Step-by-step explanation:

a = 26 m, b = 28 m, c = 30 m, s = 84/2 = 42 m.

Area = √{s(s - a)(s - b)(s - c)

Area = √42(42 - 26)(42 - 28)(42 - 30)

Area = √(42 * 16 * 14 * 12)

Area = √112896

Area = 336 m².

Cost = ₹3 * 336 = ₹1008.
