The playground is in the shape of a rectangle. To find its perimiter, we simply need to multiply its length by two and its width by two, then add the products together. The width is 18, and the length is 24, so:
\n" ); document.write( "let P=the playground's perimeter
\n" ); document.write( " $\"18%2A2%2B24%2A2=P\"$
\n" ); document.write( " $\"36%2B48=P\"$
\n" ); document.write( "84=P
\n" ); document.write( "Therefore, the playground's perimeter is 84 feet.
\n" ); document.write( "The fencing costs 12 dollars per foot, so the cost of 84 feet of fencing can be determined by multiplying the cost of one foot of fencing by the number of feet of fencing required for the playground:
\n" ); document.write( "let c=the cost of 84 feet of fencing
\n" ); document.write( " $\"12%2A84=c\"$
\n" ); document.write( " $\"1008=c\"$
\n" ); document.write( "Therefore, the fencing around the outside of the playground would cost $1008. \n" ); document.write( "

\n" );
