A rectangle is 3 times as long as it is board. If it is x cm long, find its perimeter and area in terms of x.
\n" ); document.write( "----------
\n" ); document.write( "L = x
\n" ); document.write( "W = x/3
\n" ); document.write( "------
\n" ); document.write( "P = 2L + 2W
\n" ); document.write( "P = 2x + 2x/3 = 8x/3
\n" ); document.write( "-----------
\n" ); document.write( "Area = L*W
\n" ); document.write( "= \"x%5E2%2F3\"
\n" ); document.write( "
