This math worksheet was created on 2016-04-06 and has been viewed 30 times this week and 185 times this month. Lets do this without having to rely on the formula directly. From the three pairs.
Consider the sides as x y z altitudes as p q r area as A and half the perimeter as s. Sqrt Bx-Ax2 By-Ay2 repeat this 2 more time for the other numbers now it calculates the perimeter of the triangle and halves it then inputs it into the heron formula to get the area. To use this formula you need the measure of just one side of the triangle plus the altitude of the triangle perpendicular to the base drawn from that side.
I will be computing this answer on my PC and for this method the best time complexity I could think of is O n 2. L o g n where n is the length of side.
