You can put this solution on YOUR website!
The 2ft walk is built around the outside, that means that the area will be bigger. Imagine a rectable, inside a bigger rectable. With the walk, the dimensions would be 14ft by 16ft. How did I get that?
\n" ); document.write( "Since there is a two foot extension on all sides, you need to add 4 ft because there are two sides of 2ft.
\n" ); document.write( "Then to find the area, you do the following
\n" ); document.write( "Find the area of the pool.
\n" ); document.write( " $\"10%2A12=120\"$
\n" ); document.write( "Then find the area of the pool with the walk.
\n" ); document.write( " $\"14%2A16=224\"$
\n" ); document.write( "The subtract the pool from the pool and walk to get only the walk.
\n" ); document.write( " $\"224-120=124ft%5E2\"$
\n" ); document.write( "Your final answer should be $\"124+ft%5E2\"$
\n" ); document.write( "Hope this helps! \n" ); document.write( "
