Question

Determine the perimeter of quadrilateral KLMN with vertices K(-4, 2), L(2, 2), M(8, -3), and N(-10, -6).
Answer 42 units
23.8 units
32 units
33.2 units

Answer 1

Use the distance formula between each set of adjacent points to find the length of that side of the quadrilateral:
\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
