document.write( "THE PROBLEM:\r\n" );
document.write( "You are shopping for a square fence. The area you will fence is 500 square feet. Find out how \r\n" );
document.write( "much fence you will need to buy to cover the perimeter.\r\n" );
document.write( "\r\n" );
document.write( "A SOLUTION:\r\n" );
document.write( "Let's work backwards here. You are shopping for a fence to go around a square \r\n" );
document.write( "with an area of 500 square feet. Because it is a square, each side has the same measure.\r\n" );
document.write( "\r\n" );
document.write( "Let s be the side length of the square.\r\n" );
document.write( "\r\n" );
document.write( "The formula for the area of a square is . In your problem, the area is 500 square \r\n" );
document.write( "feet, so\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This means that the side length is , or .\r\n" );
document.write( "\r\n" );
document.write( "Now, let's look at the perimeter of the square. All four sides have equal length, so the \r\n" );
document.write( "formula for the perimeter is .\r\n" );
document.write( "\r\n" );
document.write( "Substitute  for s  to give\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "You need  feet to fence the square. Now if you go to the store and ask for \r\n" );
document.write( " feet of fence, they'll think you're a crazy mathematician. This is a good time \r\n" );
document.write( "for an approximate answer. Use a calculator,\r\n" );
document.write( "\r\n" );
document.write( " is approximately \r\n" );
document.write( "\r\n" );
document.write( "You will need about 89.6 feet of fence to cover the perimeter.\r\n" );
