The 140 meters of chain-link fencing represents the perimeter of the rectangular field. Since perimeter is the sum of the lengths of a figure's sides, the perimeter of the field is width + length + length + width, or 2(width) + 2(length). Now let us find some variable expressions for the length and width:
\n" ); document.write( "width: x
\n" ); document.write( "length: x + 16 (16 meters more than the width)
\n" ); document.write( "Now plug these values for perimeter, width, and length into the equation:
\n" ); document.write( "perimeter = 2(width) + 2(length)
\n" ); document.write( "140 = 2x + 2(x + 16)
\n" ); document.write( "Distribute the 2: 140 = 2x + 2x + 32
\n" ); document.write( "Add like terms: 140 = 4x + 32
\n" ); document.write( "Subtract 32 from both sides: 108 = 4x
\n" ); document.write( "Divide both sides by 4: 27 = x
\n" ); document.write( "=> The width of the field is 27 meters.
\n" ); document.write( "To find the length, put this value in for x in the expression for length: x + 16 = 27 + 16 = 43
\n" ); document.write( "=> The length of the field is 43 meters.
\n" ); document.write( "***THEREFORE, THE LENGTH OF THE FIELD IS 43 METERS AND THE WIDTH IS 27 METERS.***
