Question

The sides of a triangle are 16 cm, 30 cm, 34 cm. Its area is​

Answer 1

Step-by-step explanation:

1/2* base * hieght

1/2*30*16

1/2*480

area equals to 240 sq cm

Answer 2

SOLUTION:-

Given:

The sides of a ∆ are 16cm, 30cm&34cm.

To find:

Area of triangle.

Therefore,

We use Heron's Formula:

⚫A= 16cm

⚫B= 30cm

⚫C= 34cm

$s = \frac{A + B + C}{2} \\ \\ = > \frac{16 + 30 + 34}{2} \\ \\ = > \frac{80}{2} \\ \\ = > 40cm$

So,

Area of triangle:

$A= \sqrt{s(s - a)(s - b)(s - c)} \\ \\ = > \sqrt{40(40 - 16)(40 - 30)(40 - 34)} \\ \\ = > \sqrt{40(24)(10)(6)} \\ \\ = > \sqrt{57600} \\ \\ = > 240 {cm}^{2}$

Hence,

The area of triangle is 240cm².
