Question
The sides of a triangle are 13 cm, 14 cm, and 15 cm.
What is the area of the triangle?Solution
We can use Heron’s formula to find the area of the triangle. First, find the semi-perimeter (s): s = (13 + 14 + 15) / 2 = 21 cm Now, use the formula for area: Area = √[s(s - a)(s - b)(s - c)] Area = √[21(21 - 13)(21 - 14)(21 - 15)] Area = √[21 × 8 × 7 × 6] Area = √[7056] Area = 84 cm² Correct Option: a) 84 cm²
