In triangle ABC, AB = 20 cm, BC = 16 cm and AC = 12 cm and the radius of circle inscribed in it is 4 cm. Find the area of triangle ABC.

96 cm²

We have a concept =

Area of triangle = Semi perimeter of triangle × radius of incircle

We have given that,

AB = 20 cm

BC = 16 cm

AC = 12 cm

Radius of incircle = 4 cm

Area of triangle = \(\frac{20 + 16 + 12}{2}\) × 4 = 96 cm²
