Question

Find the perimeter of each figure. an isosceles triangle with congruent sides of 16.2 cm and a third side half that length

Answer 1

To find the perimeter of the triangle, you will add the lengths of each side.

We know two of the sides are 16.2 cm.  We also know that the third side is half this (16.2/2) or 8.1 cm.

16.2 cm + 16.2 cm + 8.1 cm = 40.5 cm

The perimeter of the triangle is 40.5 cm.
