In the diagram, KL = , LM = , and MN = . What is the perimeter of isosceles trapezoid KLMN? units units + units + units

They give you the lengths of the sides in the problem. NM = sqrt 2, LK = 2sqrt 2, LM & NK = sqrt5 Perimeter is to add all of the sides so: sqrt2 + 2sqrt2 = 3sqrt2. sqrt5 + sqrt5 = 2sqrt5. Together it is 3sqrt2 + 2sqrt5It's letter C 3sqrt2 + 2sqrt5
