\n" ); document.write( "\n" ); document.write( "The total area is 200 times 25 square feet. If he is 82% done, he has 18% remaining. So the amount remaining is

. Let's call that quantity

\n" ); document.write( "\n" ); document.write( "If

is the dimension of the width of the strip mowed, then the dimensions of the unmowed portion must be

and

, so the area of the unmowed portion which we know has a value of

must be:\r
