A landowner wishes to construct a fence around a small section of her property. The fence is rectangular and is (3√5)/√7 meters wide and (2√3)/√5 meters long. What is the exact perimeter of the fence? (Recall that the perimeter is the sum of each individual side of a shape.)
A.√5+√3 meters
B.(3√35)/7+(2√15)/5 meters
C.(6√35)/7+(4√15)/5 meters
D.6√5+4√3 meters
I did B. and got it wrong, so I no it is not that, but when I divide the radical, I don't get any of the answers. Please help!

Also, if you can provide a walk through, that would be great.
