Question 1025901
.
W=width; L=length=2W
.
{{{L^2+W^2=(sqrt(30))^2}}}
.
{{{(2W)^2+W^2=30}}}
.
{{{4W^2+W^2=30}}}
.
{{{5W^2=30}}}
.
{{{W^2=6}}}
.
{{{W=sqrt(6)}}}
.
{{{L}}}={{{2W=2(sqrt(6))}}}
.
{{{A=LW}}}={{{sqrt(6)2sqrt(6)=2(6)}}}={{{12}}}
.
{{{A}}}={{{2sqrt(6)sqrt(6)=sqrt(6)sqrt(6)*2}}}={{{sqrt(6)*2*sqrt(6)}}}
.
