@Michele_Laino do u think u can help me out?

OpenStudy (michele_laino):

we have this ratio: \[\frac{{AE}}{{AR}} = \frac{{15}}{{12}} = \frac{5}{4}\]

OpenStudy (michele_laino):

or: \[\frac{{AR}}{{AE}} = \frac{{12}}{{15}} = \frac{4}{5}\]

OpenStudy (michele_laino):

now, we can show that the requested ratio is given by the square of the last ratio, namely: \[\frac{{area\left( {\vartriangle ARH} \right)}}{{area\left( {\vartriangle ARS} \right)}} = {\left( {\frac{{AR}}{{AE}}} \right)^2} = ...?\]

OpenStudy (michele_laino):

oops.. \[\frac{{area\left( {\vartriangle ARH} \right)}}{{area\left( {\vartriangle AES} \right)}} = {\left( {\frac{{AR}}{{AE}}} \right)^2} = ...?\]

what is the right option?
