Answer 2

Answer:

Answer is 25 cm.

Step-by-step explanation:

As it is an isosceles triangle. Therefore, its base sides are equal because its base angles are equal, i.e., AB=AC because angle A = angle B.

Therefore, Perimeter of triangle=Sum of all its sides.

=>AB+BC+CA

=>9cm+7cm+9cm { Since, AB=AC=9cm }

=25cm.
