Algebra.Com's Answer #343239 by stanbon(75887) ![]() You can put this solution on YOUR website! the perimeter of a rectangle is 126 centimeters. \n" ); document.write( "2(length + width) = 126 \n" ); document.write( "---------------------- \n" ); document.write( "the length is nine centimeters longer than the width. \n" ); document.write( "Let the width be \"W\" \n" ); document.write( "Then the length is \"W+9\" \n" ); document.write( "----- \n" ); document.write( "what are the dimensions of the rectangle \n" ); document.write( "----- \n" ); document.write( "Sustitute for the length and wide and solve: \n" ); document.write( "2(W+9 + W) = 126 \n" ); document.write( "Divide by 2 \n" ); document.write( "2W + 9 = 63 \n" ); document.write( "Subtract 9 \n" ); document.write( "2W = 54 \n" ); document.write( "Divide by 2 \n" ); document.write( "W = 27 cm (the width) \n" ); document.write( "--- \n" ); document.write( "Solve for length: \n" ); document.write( "W+9 = 36 cm (the length) \n" ); document.write( "============================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "========== \n" ); document.write( " \n" ); document.write( " |
