the answer
the full question is
In the diagram, KL =2√2 , LM =√5 , and MN = √2. What is the perimeter of isosceles trapezoid KLMN?
to find the value of the perimeter the method is as follow:
P= KL + LM + MN + KN and KN = KM (isosceles trapezoid)
P= 2√2 +√5 + √2 +√5 = 2√2 + √2 +√5 +√5= 3√2 + 2√5
the answer is 3√2 + 2√5
