Question

The side of the triangle are 3cm,5cm,6cm. What is its area?

Answer 1

A is the area of the triangle

And a,b,c are the sides of the triangle

So if a=3 cm ,b=5 cm and c=6 cm

thus , Using Heron’s Formula we get the semi-perimeter as 7 cm

and the area as

A= sqrt(7*(7–3)(7–5)(7–6))

thus A= sqrt(7*4*2*1)=sqrt(56)=7.48 sq. cm.

thus the area of the triangle with side 3 cm,5 cm and 6 cm is 7.48 sq cm.
