Heron’s formula: Area = square root 5(5-a)(5-b)(5-c) What is the area of triangle DFG? Round to the nearest whole square unit. 2
timurjin [86]
To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.

Here is an example. If the sides are 3, 4, 5.
It would be:

A= \sqrt{6(6-3)(6-4)(6-5))}

The 6 is in the formula because it is the semi-perimeter (half).
