Step-by-step explanation:

To find perimeter, you need to add all the sides of the shape.

The area of a traingle is 1/2 bh.

You must find the "b" in order to find the perimeter.

Example:

A triangle has an area of 18 cm^2.

Therefore, the triangle has a 6 cm base and 6 cm height.

Then multiply the base by three to get 18 cm. That is your perimeter.
