Question

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

42 units

23.8 units

32 units

33.2 units

Answer 1

Side KL is 6 units (x changes 6 units, y no change)

Side LM is ~7.81 units (x changes 6 units, y changes 5 units; square and add both of these changes, then take the square root of the total)

Side MN is ~18.25 units (x changes 18 units, y changes 3 units)

Side NK is 10 units (x changes 6 units, y changes 8 units)

42 units is the closest answer.
