For this case we have a quadratic equation, , of the form
Where:
We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.
These numbers are:
Then, the factorization is given by:
The roots are:
Answer:
the perimeter will then just be the sum of the distances of A, B and C, namely AB + BC + CA.
