$\huge{\underline{\underline {\mathtt{\purple{ą}\pink{ŋ}\green{ʂ}\blue{ῳ}\red{ɛ}\orange{ཞ}}}}}$

Given :-

1st side - 150cm

2nd side - 120cm

3rd side - 20 cm

To Find :-

Area of given triangle

Formula :-

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

We know that :-

$s \: is \: semi \: perimeter$

Solution :-

$s \: = \frac{150 + 120 + 20}{2}$

$s \: = 280$

$\sqrt[]{280(280 - 150)(280 - 120)(280 - 20)}$

$\sqrt[]{280 \times 130 \times 160 \times 260}$

$90493148.4$
