We have a right triangle of height h, width h+2, and hypotenuse sqrt(6).
\n" ); document.write( "a^2+b^2=c^2
\n" ); document.write( "h^2+(h+2)^2=sqrt(6)^2
\n" ); document.write( "h^2+h^2+4h+4=6
\n" ); document.write( "2h^2+4h-2=0
\n" ); document.write( "2(h^2+2h-1)=0
\n" ); document.write( "h^2+2h =1
\n" ); document.write( "h^2+2h+1=1+1 completing the square.
\n" ); document.write( "(h+1)^2=2
\n" ); document.write( "h+1=+-sqrt(2) Square root of each side.
\n" ); document.write( "h= -1+sqrt(2) m
\n" ); document.write( "w= 1+sqrt(2) m
\n" ); document.write( ".
