N is the midpoint of MH, and ML = 15 in the square LMNK. If AK = 25, which is the measure of GH in the rectangle ANHG?

 

You're given that                       ML  =  15

Since LMNK is a square,           KN  =  15   

You're given that                       AK  =  25        

Therefore AK + KN =                 AN  =  40       

Since ANHG is a rectangle,       GH  =  40
