Find the area of a parallelogram bounded by the y-axis, the line
\n" ); document.write( "\"x+=+4\",\r

\n" ); document.write( "\n" ); document.write( "\"f%28x%29+=+4+%2B+2x\"\r
\n" ); document.write( "\n" ); document.write( "and the line parallel to \"f%28x%29\" passing through (\"2\", \"6\").\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The line parallel to \"y=4+%2B+2x\" will be of the form \r
\n" ); document.write( "\n" ); document.write( "\"y=2x%2Bk\"\r

\n" ); document.write( "\n" ); document.write( "\"k=2\"\r
\n" ); document.write( "\n" ); document.write( "and hence two parallel lines have equations \r

\n" ); document.write( "As the difference in y-intercepts is \"2\",the side of parallelogram along y-axis is\"+2\"
\n" ); document.write( ".
\n" ); document.write( "Further, two other parallel lines are \"x=0\" and \"x=4+\"and hence vertical distance between them is \"4\"\r

\n" ); document.write( "\n" ); document.write( "the vertices of the parallelogram are: \r

\n" ); document.write( "\n" ); document.write( "The edges AB and CD can be considered the bases; then the length of the bases is \"2\" and the height is \"4+\"(the horizontal distance between AB and CD).\r
