LEVEL-1
1. Find the area of a triangle whose sides are respectively 150 cm, 120 cm and 200 cm?
plzz give step by step solution..​

Answer 1

Step-by-step explanation:

By heron's formula:

Area= a+ b+ c / 2

s= 150+120+200/2

= 470/2

= 235

so, area =

$\sqrt{s(s - a)(s - b)(s - c)}$

$\sqrt{235(235 - 150)(235 - 120)(235 - 200)}$

$\sqrt{235 \times 85 \times 115 \times 35}$

$\sqrt{80399375}$

=

${8966.57 \: cm}^{2}$
