Question

In ΔABC, AB = 20 cm, BC = 16 cm and AC = 12 cm and the radius of incircle is 4 cm. Find the area of ΔABC.

• A. 88
• B. 96
• C. 84
• D. 92

Answer 1

Answer:

B. 96

AB = 20 cm BC = 16 cm AC = 12 cm Radius of incircle = 4 cm Area of triangle = semi–perimeter of triangle × radius of incircle Area of triangle = [(20 + 16 + 12)/2] × 4 = 96
