please anyone give answer​

Answer 1

$\huge{☞︎︎︎ \: solution}$

❥︎. The sides of triangle are in ratio12 : 17 : 25.

Perimeter = 540cm

=> 12x + 17x + 25x = 540

=> 54x = 540

=> X = 10

Now, 1st side = 12 × 10= 120

2nd side = 17 × 10 = 170

3rd side = 25 × 10 = 250

Now, we have to find the value of s.

So, s = Perimeter/2

= 540/2

= 270

Formula of area of triangle:

$Area \: of \: triangle = \sqrt{s \: (s - a)(s - b)(s - c)}$

$= \sqrt{270(270 - 120)(270 - 170)(270 - 250)}$

$= \sqrt{270 \times 150 \times 100 \times 20)}$

$= \sqrt{3 \times 3 \times 3 \times 5 \times 2 \times 5 \times 3 \times 5 \times 2 \times 5 \times 2 \times 5 \times 2 \times 5 \times 4}$

$= \ \sqrt{ {3}^{2} \times {3}^{2} \times {5}^{2} \times {2}^{2} \times {5}^{2} \times {2}^{2} \times {5}^{2} \times {2}^{2} }$

$= \sqrt{9 \times 10 \times 10 \times 10}$

$= 9000 \: {cm}^{2}$
