Question

The side of a triangle are all the same length if the length of one of the side is 2cm, what is the perimeter of the triangle?

Answer 1

If all sides of the triangle are the same length and one side is 2cm, then the other two sides must also be 2cm each.

Perimeter = sum of all sides
Perimeter = 2cm + 2cm + 2cm = 6cm

Therefore, the perimeter of the triangle is 6cm.
