Question

if the side of a triangle are 3 cm , 4 cm and 5 cm then find the area of the triangle​

Answer 1

Answer:

$s \: = \: \frac{a + b + c}{2} \\ s = \frac{3 + 4 + 5}{2} \\ s = \frac{12}{2} \\ s = 6 \: \\ area \: = \sqrt{s(s - a)(s - b)(s - c} \\ = \sqrt{6(6 - 3)(6 - 4)(6 - 5)} \\ = \sqrt{6 \times 3 \times 2 \times 1} \\ = \sqrt{36} \\ area = 6 \: {cm}^{2} \\ \\ follow \: \: me \: \: guys$
