Question 882589
The diagonal is the hypotenuse of right triangle using the given rectangle sides.
2:1, {{{2/1=2x/1x}}}.


{{{(2x)^2+x^2=23^2}}}
{{{3x^2=23^2}}}
{{{x^2=(23/3)^2}}}-----you could actually use this to finish the solution
{{{x=sqrt(23)/sqrt(3)}}}
{{{x=sqrt(69)/3}}}, and you can say the other side length, {{{2x=(2/3)sqrt(69)}}}


Area of the rectangle is {{{x*2x=2x^2=2*(23/3)^2=highlight(529/9=58&7/9)}}}
