Answer 2

Given : -

Sides of triangle = 3cm , 5cm , 6cm

To Find : -

Area of the triangle.

Answer : -

Here ,

• a = 3
• b = 5
• c = 6

Now :

$\sf{Area=\sqrt{s(s-a)\:(s-b)\:(s-c)}}$

= √ 7(7-3) (7-5) (7-6)

= √ 7 × 4 × 2 × 1

= √ 7 × 2 × 2 × 2

= 2 √14cm²

So , the area of the triangle is 2 √14cm² ..
