Question

Find the exact perimeter of triangle ABC.

Answer 1

Perimeter of triangle ABC is $6 \sqrt{5}+6$ m.

Solution:

Given data:

AB = $3 \sqrt{5}$ m

BC = $3 \sqrt{5}$ m

CA = 6 m

Perimeter = Sum of all the sides

Perimeter of triangle ABC = AB + BC + CA

                                           $=3 \sqrt{5}+3 \sqrt{5}+6$

                                           $=6 \sqrt{5}+6$ m

Perimeter of triangle ABC is $6 \sqrt{5}+6$ m.
