Find the perimeter and area of △LMN with L(5,5), M(-2,-4), and N(5,-6)

Answer 1

The perimeter is the distance around sides LM, MN, and NL. Use the distance formula (look it up in your text or on-line) to measure the distances between points L and M, then points M and N, and finally points N and L. Then add the three distances together to get the perimeter.
