By definition a square has four equal sides.
\n" ); document.write( "The Perimeter of a square is the addition of the four sides.
\n" ); document.write( "The length of one side of the square would then be $\"X%2F4\"$
\n" ); document.write( "The area of a rectangle (or square) is given by A = L x W
\n" ); document.write( "Where L is the length of the rectangle and W is the width
\n" ); document.write( "For the square: $\"A+=+%28X%2F4%29%2A%28X%2F4%29\"$
\n" ); document.write( "Which can be rewritten as $\"A+=+X%5E2%2F16\"$
\n" ); document.write( "This was done by multiplying both numerators together. And multiplying both denominators together.
\n" ); document.write( "-------------
\n" ); document.write( "If X = 10
\n" ); document.write( " $\"A+=+X%5E2%2F16\"$
\n" ); document.write( " $\"A+=+%2810%29%5E2%2F16\"$
\n" ); document.write( " $\"A+=+100%2F16\"$
\n" ); document.write( " $\"highlight%28A+=+6.25cm%5E2%29\"$ \n" ); document.write( "

\n" );
