Question 1138743
( 2/3 ) / 1 is the same as 2/3
Let the height  = {{{ x }}}
{{{ 2x }}} = sum of both verticals
{{{ 120 - 2x }}} = the sum of both horizontals
{{{ ( 120 - 2x )/2 = 60 - x }}} is the width
and
{{{ 2/3 = x / ( 60 - x ) }}}
{{{ 2*( 60 - x ) = 3x }}}
{{{ 120 - 2x = 3x }}}
{{{ 5x = 120 }}}
{{{ x = 24 }}}
and
{{{ 60 - x = 36 }}}
------------------------
The picture is 24 x 36
------------------------
check:
{{{ 2*24 = 48 }}}
{{{ 2*36 = 72 }}}
{{{ 48 + 72 = 120 }}}
OK
