a rectangle has a length that is three times its width. the diagonal of the rectangle is 50cm. find the width of the rectangle
\n" ); document.write( "..
\n" ); document.write( "width = x
\n" ); document.write( "length = 3x
\n" ); document.write( "diagonal D = 50
\n" ); document.write( "...
\n" ); document.write( "By Pythagoras theorem
\n" ); document.write( "D^2= x^2+(3x)^2
\n" ); document.write( "D^2=x^2+9x^2
\n" ); document.write( "D^2=10x^2
\n" ); document.write( "50^2= 10x^2
\n" ); document.write( "2500/10= x^2
\n" ); document.write( "250 = x^2
\n" ); document.write( "x= 15.8 cm the width
