The length of a rectangle is 4 times the width. The area 144in squared. find the length and width of the rectangle.
\n" ); document.write( "let w = width
\n" ); document.write( "l=length
\n" ); document.write( "l=4w
\n" ); document.write( "so we have length= 4w
\n" ); document.write( "and width =w
\n" ); document.write( "area equals length times width
\n" ); document.write( "144 sq in =4w*w
\n" ); document.write( "144=4w^2
\n" ); document.write( "36=w^2
\n" ); document.write( "6=w
\n" ); document.write( "width=6 inches
\n" ); document.write( "length=4w=24 inches\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
