Question

sides of a triangle with 2:3:4 find the area​

Answer 1

Answer:

$\sqrt[3]{15}$

Explanation:

$a = 2 \\ b = 3 \\ c = 4 \\ perimeter = 18cm \\ a + b + c = 18cm \\ 2x + 3x + 4x = 18cm \\ ax = 18 \\ x = 2cm \\ = a = 4cm \\ b = 6cm \\ c = 8cm \\ semi \: perimeter \: s = \frac{a + b + c}{2} \\ s = 9cm \\ = \sqrt{s(s - a)(s - b)(s - c)} \\ = \sqrt{9(9 - 4)(9 - 6)(9 - 8)} \\ = \sqrt{9(5)(3)(1)} \\ \sqrt[3]{15}$
