The perimeter of a rectangular dining room is 18 meters. The area is 18 square meters. What are the dimensions of the dining room?
\n" ); document.write( "

Let length and width be L and W, respectively
\n" );
document.write( "Then we get: 2(L + W) = 18_______2(L + W) = 2(9)______L + W = 9______L = 9 - W ---- eq (i)
\n" );
document.write( "Also, LW = 18 ------ eq (ii)
\n" );
document.write( "W(9 - W) = 18 ------ Substituting 9 - W for L
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "0 = (W - 6)(W - 3)
\n" );
document.write( "W - 6 = 0             OR                 W - 3 = 0
\n" );
document.write( "W, or width = 6       OR                 W = 3
\n" );
document.write( "If width = 6, then length = 3(9 - 6), and VICE-VERSA.
\n" );
document.write( " \n" );
