use Pythagorean Theorem
c%5E2+=+a%5E2+%2B+b%5E2
if one leg of a right triangle is a=6+m and the hypotenuse is c=12+m, the approximate length of the second leg b is:
c%5E2+=+a%5E2+%2B+b%5E2
%2812+m%29%5E2+=+%286+m%29%5E2+%2B+b%5E2
b%5E2+=+%2812+m%29%5E2+-+%286+m%29%5E2
b%5E2+=+144m%5E2+-+36m%5E2
b%5E2+=+180m%5E2+

b+=+sqrt%28180m%5E2%29+
b+=+13.416m+

the approximate length of the second leg is b+=+13m+
