Area of triangle = sqrt[p/2*(p/2-a)*(p/2-b)*(p/2-c)] where a, b and c are the sides.
p = r - c r - c = p r - c - r = p - r -(-c) = -(p) c = -p
5 points for a try and 2 points for a conversion.
p=b+3a+c p-3a-c=b+3a-3a+c-c p-3a-c=b b=p-3a-c
If we're talking strictly algebra. 12 equals p of c can be written as: 12= p(c) meaning, 12 is the answer for some function p, when c is the variable.
