the length of a rectangle is 3 meters less than twice the width.if the area is 464 square meters,find the dimensions 464.\r

\n" ); document.write( "Let l-the length
\n" ); document.write( " w-the width\r
\n" ); document.write( "\n" ); document.write( "l=2w-3 ----(1)
\n" ); document.write( "lw=464 ----(2)\r
\n" ); document.write( "\n" ); document.write( "substitute (1) into (2)
\n" ); document.write( "w(2w-3)=464
\n" ); document.write( "2w^2-3w-464=0
\n" ); document.write( "factor:
\n" ); document.write( "(w-16)(2w+29)=0
\n" ); document.write( "take w = 16m, then substitute to (1).
\n" ); document.write( "l=2(16)-3 = 29
\n" ); document.write( "thus, the dimension is
\n" ); document.write( "29m x 16m -----answer\r
