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
The perimeter is equal to
substitute the values
3 StartRoot 2 EndRoot + 2 StartRoot 5 EndRoot units
