Question

The perimeter P of a triangle is equal to the sum of the lengths of sides AB and C

Answer 1

P = a + b + c

Explanation:

A triangle has 3 sides. Perimeter is the measurement of the length around a shape. If you add sides A, B, and C, you will get the perimeter. You can also find a missing side by subtracting two known sides of the triangle if you know the perimeter.
