This rectangular prism is intersected by a plane that contains points D, E, K, and L.

 

What is the perimeter of the cross section?

Edges  EK  and  DL  of the plane = sqrt (5^2 + 4^2)  =  sqrt (41) m

 

And edges DE  and KL  of the plane  =  12 m

 

So.....the perimeter of  DEKL  = 2 ( sqrt (41)  + 12)  ≈  36.81 m
