Let: L=Length and W=Width \n" ); document.write( "Perimeter = 2L + 2W \n" ); document.write( "W = L – 12 … width 12 units less than length \n" ); document.write( "108 = 2L + 2(L-12) \n" ); document.write( "108 =2L + 2L - 24 \n" ); document.write( "108 = 4L - 24 \n" ); document.write( "108 + 24 = 4L -24 + 24 \n" ); document.write( "132 = 4L \n" ); document.write( "132/4 = 4L/4 \n" ); document.write( "33 = L \n" ); document.write( " \n" ); document.write( " |
