Answer 2

Answer:

$\small\underline\textsf{\orange{Side} \blue{of }\red{triangle} = \purple{40cm}}$

$\large\underline\textsf{To Find }$

$\small\textsf{the\: length \:of \:the\: side \:of \:a\: triangle }$

$\huge\underline\textsf{Explantion:- }$

$\leadsto\bf area \: of \: square = (10) {}^{2}$$\leadsto\bf area \: of \: square = 100cm {}^{2}$

$\huge\underline\textsf{ Formula\: Used}$

$\boxed{\bf\red{Area \: of \: Base = \frac{1}{2} \times base \times Hieght}}$

$\implies\bf area \: of \: triangle = 100cm {}^{2}$

$\small\underline\textsf{ suppose the base of triangle \red{be Y}}$

$\small\underline\textsf{hieght=5}$

$\rule{300}{2}$

$\leadsto\sf100 = \frac{1}{2} \times y \times 5$

$\leadsto\sf 100 \times 2 = 5y$

$\leadsto\sf \frac{\cancel{200}}{\cancel5}$

$\leadsto\sf40 = y$

$\leadsto\sf y = 40cm$

$\underline{\underline{\underline{\boxed{\boxed{\boxed{\bf{ The \:side\: of \:Triangle \:= 40cm}}}}}}}$
