The perimeter formula of a rectangle is 2 times its length plus 2 times its width.
\n" ); document.write( "2(length) + 2(width) = perimeter
\n" ); document.write( "We are told to use x to represent the width.
\n" ); document.write( "And that the length is 12 feet more than the width. So:
\n" ); document.write( "the length = x + 12
\n" ); document.write( "We are also given the perimeter is 100 feet so if we substitute all this information in to the perimeter formula we get:
\n" ); document.write( "2(x + 12) + 2x = 100\r
\n" ); document.write( "\n" ); document.write( "Now you can solve for width x
\n" ); document.write( "2(x + 12) + 2x = 100
\n" ); document.write( "2x + 24 + 2x = 100
\n" ); document.write( "4x + 24 = 100
\n" ); document.write( "4x = 76
\n" ); document.write( "x = 19
\n" ); document.write( "So the width is 19 feet
\n" ); document.write( "and to find the length
\n" ); document.write( "length = x + 12
\n" ); document.write( "length = 19 + 12
\n" ); document.write( "length = 31
\n" ); document.write( "So the length is 31 feet\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
