NEED TO KNOW:
\n" ); document.write( "PERIMETER IS THE TOTAL LENGTH OF ALL FOUR SIDES\r
\n" ); document.write( "\n" ); document.write( "LET \"L\" REPRESENT THE LENGTH OF THE BASE AND \"H\" BE THE HEIGHT OF THE RECTANGLE
\n" ); document.write( "ACCORDING TO THE QUESTION, THE FOLLOWING IS TRUE.
\n" ); document.write( "\"L=3%2AH\"
\n" ); document.write( "TOTAL LENGTH OF ALL FOUR SIDES IS 72cm
\n" ); document.write( "\"L%2BL%2BH%2BH=72cm\"
\n" ); document.write( "SUBSTITUTE FOR L
\n" ); document.write( "\"%283%2AH%29%2B%283%2AH%29%2BH%2BH=72cm\"
\n" ); document.write( "SOLVE:
\n" ); document.write( "SIMPLIFY:
\n" ); document.write( "\"8H=72cm\"
\n" ); document.write( "DIVIDE BOTH SIDES OF THE EQUATION BY 8
\n" ); document.write( "\"H=highlight%289cm%29\"
\n" ); document.write( "\"L=3%2A9cm\"
\n" ); document.write( "\"L=highlight%2827cm%29\"\r
\n" ); document.write( "\n" ); document.write( "check your answer!!
\n" ); document.write( "\"27cm%2B27cm%2B9cm%2B9cm=72cm\"
\n" ); document.write( "
