Help plzzzzzzzzzzzzzzzzz

In the diagram, KL = 2 StartRoot 2 EndRoot, LM = StartRoot 5 EndRoot, and MN = StartRoot 2 EndRoot. What is the perimeter of isosceles trapezoid KLMN? StartRoot 2 EndRoot units StartRoot 5 EndRoot units 3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units 4 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Explanation:

we know that

The isosceles trapezoid has :

Two parallel sides not equal in length called its bases (KL and NM)

Two non-parallel sides equal in length (LM and NK)

so


NK=√(5)\ units

The perimeter is equal to


P=KL+LM+NM+NK

substitute the values


P=2√(2)+√(5)+√(2)+√(5)


P=(3√(2)+2√(5))\ units

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
