Question 1202923
small rectangle
dimensions 4 and 6
perimeter  {{{2*4+2*6}}}


large rectangle
dimensions x and y
perimeter {{{2x+2y}}}


Ratio of Perimeters is 2 to 3.
{{{(2*4+2*6)/(2x+2y)=2/3}}}


As given, these rectangles are also SIMILAR.
{{{4/6=2/3=x/y}}}.


system can be {{{system((4+6)/(x+y)=2/3,2/3=x/y)}}}.


{{{system(10/(x+y)=2/3,2/3=x/y)}}}


{{{system(30=2x+2y,3x=2y)}}}


simple substitution is obvious.
{{{30=2x+3x}}}-----from which,..... !
