The other leg is:
+sqrt%28+13%5E2+-+5%5E2+%29+
+sqrt%28+169+-+25+%29+
+sqrt%28+144+%29+=+12+
The perimeter is:
+5+%2B+12+%2B+13+=+30+

the perimeter of a right angle triangle is
P=a%2Bb%2Bc
if one leg of a=5ft and a hypotenuse of c=13ft, we can find other leg using Pythagorean theorem:
c%5E2=a%5E2%2Bb%5E2
b%5E2=c%5E2-a%5E2
b%5E2=%2813ft%29%5E2-%285ft%29%5E2
b%5E2=169ft%5E2-25ft%5E2
b%5E2=144ft%5E2
b=sqrt%28144ft%5E2%29
b=12ft
then
P=a%2Bb%2Bc
P=+5ft%2B12ft%2B13ft
P=+30ft
