Whats a Spread again?

Here is a triangle with side lengths 3,4, and 2. Find the sum of the three spreads associated with this triangle then take the sum of the numerator and the denominator, in its reduced form, as the answer.

Here is the cross law to help you out: $(Q_1+Q_2-Q_3)^2=4Q_1Q_2c_3$

Remember! That that the $quadrance$ can be considered the distance squared and that the $spread$ is just a measure of separation between the two lines in consideration. Also, $cross + spread = one$ . Lots to think about! Good luck!
