the length of the side parallel to the x-axis is the difference in the x's when the y is constant
\n" ); document.write( "__ similarly with the side parallel to the y-axis\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x-length __ -0.1-(-7.9) __ 7.8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y-length __ 6.8-(-3.4) __ 10.2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "area is 7.8*10.2 __ 79.56
