Step-by-Step Solution
Equal tangents: AF = AD = 4, BD = BE = 5, CE = CF = 6. Perimeter = 2(4 + 5 + 6) = 30 cm. 15 cm counts each tangent length once.
Answer: A) 30 cm
A circle is inscribed in triangle ABC, touching AB at D, BC at E and CA at F. If AD = 4 cm, BE = 5 cm and CF = 6 cm, find the perimeter of the triangle.
