length is 2 centimeters less than the 7 times the width.
\n" ); document.write( "let l = length
\n" ); document.write( "let w = width
\n" ); document.write( "l = 7w - 2
\n" ); document.write( "perimeter = 60 cm = 2 * (length + width) = 2 * (l + w).
\n" ); document.write( "since l = 7w - 2, then perimeter = 2 * (7w - 2 + w).
\n" ); document.write( "combine like terms to get perimeter = 2 * (8w - 2).
\n" ); document.write( "simplify to get perimeter = 16w - 4.
\n" ); document.write( "since perimeter = 60 centimeters, then 60 = 16w - 4
\n" ); document.write( "add 4 to both sides of this equation to get 64 = 16w
\n" ); document.write( "solve for w to get w = 64 / 16 = 4.
\n" ); document.write( "since l = 7w - 2, then l = 7*4 - 2 = 28 - 2 = 26.
\n" ); document.write( "you have length = 26 and width = 4.
\n" ); document.write( "perimeters = 2 * (length + width) = 2 * (26 + 4) = 2 * 30 = 60.
\n" ); document.write( "solution is confirmed to be good.
\n" ); document.write( "width = 4
\n" ); document.write( "length = 26\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
