Algebra.Com's Answer #232216 by graphmatics(170) You can put this solution on YOUR website! If x is the length of the rectangle then the width of the rectangle y = x-3. The perimeter is twice the width plus twice the length so 2*x + 2*(x-3) = 50. We solve this equation for x.\r \n" ); document.write( "\n" ); document.write( "2*x + 2*(x-3) - 50 \n" ); document.write( "2*x + 2*x - 2*3 = 50 \n" ); document.write( "4*x -6 = 50 \n" ); document.write( "4*x = 50 + 6 \n" ); document.write( "4*x = 56 \n" ); document.write( "x - 56/4 \n" ); document.write( "x = 14\r \n" ); document.write( "\n" ); document.write( "so y = 14 - 3 \n" ); document.write( " y = 11\r \n" ); document.write( "\n" ); document.write( "So the length is 14 and the width is 11. \n" ); document.write( " |
