Answer 2

$\huge\mathscr\pink{Answer}$

ANS 1)

$A \: = 20</h2><h2>$

$</h2><h2>B \: = 50</h2><h2></h2><h2>$

$</h2><h2>C = 50</h2><h2>$

$s \: = \frac{a + b + c}{2}$

$s \: = \: \frac{20 + 50 + 50}{2}$

$s \: = \cancel \frac{120}{2}$

$s \: = \: 60$

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

$\sqrt{60 \: (60 - 20) \: (60 - 50) \: (60 - 50)}$

$\sqrt{60 \times 40 \times 10 \times 10}$

$\sqrt{6 \times 10 \times 2 \times 2 \times 10 \times 10}$

$10 \times 10 \times 2 \sqrt{6}$

$200 \sqrt{6}$

$Area \: of \: 1 \: color \: = \: 5$

$5 \times 200 \sqrt{6}$

$100 \sqrt{6 \: } {m}^{2}$

$</h2><h2>Area \: of \: 2 \: \: color \: = \: 5$

$5 \times 200 \sqrt{6}$

$1000 \sqrt{6} cm$
