I think you're asking about the perimeter of the triangle,
Use half the base and the height to calculate the side length using the Pythagorean theorem,
%28B%2F2%29%5E2%2BH%5E2=S%5E2
Convert all units to inches.
%2860%2F2%29%5E2%2B18%5E2=S%5E2
S%5E2=900%2B324
S%5E2=1224
S=sqrt%281224%29
S=6sqrt%2834%29
So then,
P=S%2BS%2BB
P=12sqrt%2834%29%2B60
P=60%2B12sqrt%2834%29inches
