Answer 2

$\huge{\underline{\underline{\red{♡Solution→}}}}$

______________________________________

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

Sides -

a = 150 cm

b = 120 cm

c = 2 m = 2×100 = 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.

$p = \frac{150+120+200}{2} \\ p = \frac{470}{2}$

$p = 235$

Now Area is ,

$a = \sqrt{235(235-150)(235-120)(235-200)} \\ a = \sqrt{235 \times 85 \times 115 \times 35}$

$a = \sqrt{80399375}$

$\boxed{a = 8,966.56986}$
