__________________________

$\bold{\huge{\underline{\underline{\rm{ Given :}}}}}$

Sides -

a = 180 cm

b = 120 cm

c = 200 cm

$\bold{\huge{\underline{\underline{\rm{ To\:Find :}}}}}$

Area of Triangle .

__________________________

The herons formula to find Area of Triangle is :

$area(a) = \sqrt{p(p - a)(p - b)(p - c)}$

Where P is half perimeter.

$p = \frac{a + b + c}{2}$

__________________________

$\purple{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

First find out the value of P →

$p = \frac{180+120+200}{2} \\ p = \frac{500}{2}$

$p = 250$

Now Area is ,

$a = \sqrt{250(250 - 180)(250 - 120)(250 - 200)} \\ a = \sqrt{250 \times 70 \times 130 \times 50}$

$a = \sqrt{113,750,000}$

$\boxed{\red{a =10,665.3645 }}$
