Question

KLMN with vertices K (-3,-3), L (-1,-3), M (1,4), and N (-3,1). Find the perimeter of KLMN

Answer 1

11 + sqrt(53)

Explanation:

Lengths

KL = -1 - (-3) = 2

LM = sqrt[(4--3)² + (1--1)²]

= sqrt(53)

MN = sqrt[(1-4)² + (-3-1)²]

= 5

NK = 1 - (-3) = 4

Perimeter = 2 + sqrt(53) + 5 + 4

11 + sqrt(53)
