Answer 2

Given,

Three sides of triangle of 60 m , 80 m, 100 m each.

To Find,

Area of the Triangle.

Solution,

Area of Triangle = $\sqrt{S(S-a)(S-b)(S-c)}$

Where S = Semi Perimeter of Triangle

a, b and c are sides of triangle

and S= $\frac{a+b+c}{2}$

let us say a = 60 m, b = 80 m and c = 100 m

Thus S = $\frac{60+80+100}{2}$ = $\frac{240}{2}$ = 120

Thus area of triangle = $\sqrt{120(120-60)(120-80)(120-100)}$

⇒ $\sqrt{(120)(60)(40)(20)} = 2400$

Henceforth the area of triangle is 2400 sqmtrs
