Compute the area using Herons formula below in which s represents half of the perimeter of the triangle and a b c represent the lengths of the three sides. Makes trig so much easier lowkey. S abc 2.
What the unit of measurement is exactly is not important.
Since Herons formula relates the side lengths perimeter and area of a triangle you might need to answer more challenging question types like the following example. Herons formula is used to find the area of a triangle when we know the length of all its sides. Both of which are special cases of Bretschneiders formula for the area of a quadrilateral. S abc2 Area S x S - a x S - b x S - c Where a Side A b Side B c Side C S Area of Triangle.
