Question

cost of levelling the ground in the form of a triangle having sides 51 m 37 m and 220 m at rupees 3 per metre square is ​

Answer 1

Step-by-step explanation:

Hey,.

Area of the triangular field ...using heron's formula,

semi perimeter=51+37+20/2=54m

So, area = √s(s-a) (s-b) (s-c)

=√54(54-51)(54-37)(54-20)

=√54*3*17*34

=√93636

=306m^2.

So, now, cost of levelling = area * rate

980=306*3

980 = 918

Therefore, since, cost of levelling the field at the rate of Rs 3 per square is not Rs 980.And so the given statement is false.
