<prompt> Calculate the area of a triangle with the given side lengths.A 8 cm, B 6 cm, C 4 cm  <response>: We can use Herons Formula to calculate the area of a triangle, given the length of its three sides. According to this formula, the area of a triangle can be calculated by:- First, calculating the semi-perimeter s A B C 2, where A, B, and C are the side lengths.- Then, plugging the values of s, A, B, and C into the formula: area ss-As-Bs-CSo, given the side lengths A 8 cm, B 6 cm, and C 4 cm:- The semi-perimeter is s A B C 2 8 6 4 2 9 cm- So the area of the triangle will be: ss-As-Bs-C 99-89-69-4 9 × 1 × 3 × 5 135 315 cm2The area of this triangle is 315 cm2.
