Help plzzzzzzzzzzzzzzzzz
bixtya [17]

Answer:

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units

Step-by-step 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=\sqrt{5}\ units

The perimeter is equal to

P=KL+LM+NM+NK

substitute the values

P=2\sqrt{2}+\sqrt{5}+\sqrt{2}+\sqrt{5}

P=(3\sqrt{2}+2\sqrt{5})\ units

3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
