What is the perimeter of a triangle ABC with sides AB = BC = 4cm, AC = 7cm3mm?

In order to find the perimeter of a triangle, we need to add the lengths of all its sides.

According to the formula for finding the perimeter of a triangle, the perimeter of a given triangle ABC will be:

P = AB + BC + AC.

Let us calculate what the perimeter is equal to, if from the condition of the problem we know that AB = BC = 4 cm, and the AC side = 7 cm 3 mm.

P = 4 + 4 + 7.3 = 15.3 cm or 15 cm 3 mm.

Answer: The perimeter of this triangle ABC is 15 cm 3 mm.
