Question

the ratio of corresponding side or similar triangle is 3:5; then find ratio of their area​

Answer 1

$let \: the \: corresponding \: sides \: of \: similar \: \\ triangles \: be \: a : b = 3 : 5$

$since \: the \: triangles \: are \: similar \: then \:$

$( \frac{a}{b} )^{2} = ( \frac{3}{5} )^{2} = \frac{9}{16}$

$so \: the \: ratio \: is \: \boxed{ \green{9 : 16}}$

Answer 2

Answer:

$let \: thecorresponding \: sides \: of \: similar \: triangles \: be \: a:b=3:5 \: </p><p>since \: the \: triangles \: are \: similar \: then \:since \: the \: triangles \: are \: similar \: then</p><p></p><p>( \frac{a}{b} )^{2} = ( \frac{3}{5} )^{2} = \frac{9}{16}(ba)2=(53)2=169</p><p></p><p>so \: the \: ratio \: is \: \boxed{ \green{9 : 16}}</p><p></p><p>$
