\n" ); document.write( "\n" ); document.write( "The perimeter of a rectangle is the sum of twice the length and twice the width. In algebraic form, here it is:
\n" ); document.write( "Perimeter = 2L + 2W
\n" ); document.write( "If the length is 80 more than the width, then we just substitute l with W+80:
\n" ); document.write( "Perimeter = 2(W+80) + 2W = 200
\n" ); document.write( "2W + 160 + 2W = 200
\n" ); document.write( "4W = 200 - 160 = 40
\n" ); document.write( "\n" ); document.write( "\n" ); document.write( "
W = 10 yards
\n" ); document.write( "L = 90 yards
