Question

find the perimeter of triangle ABC in which ab is equals to 10 .2 cm, BC is equals to 17.5 cm and AC is equals to 15.3 CM​

Answer 1

43 cm

Explanation:

Given,

Sides of triangle ABC = 10.2cm, 17.5cm and 15.3cm

As we know,

Perimeter of a triangle = a + b + c

• [Where, a, b and c are the three sides of the triangle]

Therefore,

Perimeter of triangle ABC

= 10.2 cm + 17.5 cm + 15.3 cm

• [On adding]

= 43

Hence,

The reqiured perimeter of triangle ABC is 43cm (Ans)
