NEED TO KNOW:
\n" ); document.write( "AREA OF A RECTANGLE = L*W
\n" ); document.write( "QUESTION STATES THE FOLLOWING TO BE TRUE
\n" ); document.write( "\"L=5%28W%29\" AND THAT THE AREA IS \"245cm%5E%282%29\"
\n" ); document.write( "SUBSTIUTE FOR L IN AREA FORMULA: \"L%2AW=245cm%5E%282%29\"
\n" ); document.write( "\"5%28W%29%28W%29=245cm%5E%282%29\"
\n" ); document.write( "\"5W%5E%282%29=245cm%5E%282%29\"
\n" ); document.write( "SIMPLIFY:
\n" ); document.write( "DIVIDE BOTH SIDES OF THE EQUATION BY 5
\n" ); document.write( "\"W%5E%282%29=+49cm%5E%282%29\"
\n" ); document.write( "\"W=highlight%287cm%29\"
\n" ); document.write( "\"L=5%287%29\"
\n" ); document.write( "\"L=+highlight%2835cm%29\"
\n" ); document.write( "PERIMETER IS THE TOTAL LENGTH OF ALL SIDES
\n" ); document.write( "\"PERIMETER=+7%2B7%2B35%2B35\"
\n" ); document.write( "\"PERIMETER=highlight%2884cm%29\"
\n" ); document.write( "
