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
