Question

A triangular field has sides pf 120 80 and 50 meters what is the atea

Answer 1

area of ∆= (Height x Base)/2

Answer 2

Heya..!
Here is ur answer..!

This question can be solved by using the Heron’s Formula.

Firstly, we will have to find the perimeter of the triangular field.

120+80+50=250

Now, half the area. The value which we will get after halving the area is called as the Semi Perimeter or simply, (s).

s=250/2
=125

So, here comes the Heron's formula..

√s(s-a)(s-b)(s-c)
=√125(125-120)(125-80)(125-50)
=√125(5)(45)(75)
=√5×5×5×5×5×3×3×5×5×3
=5×5×5×3√3×5
=135√15m^2

Hope this clarified ur doubt...!
