Abby drew a scale drawing to represent her living room. The drawing is rectangular. The longer sides measure 40.5 centimeters and the shorter sides measure 34.5 centimeters. Abby decides she wants the drawing to be smaller. She will reduce it by a scale factor of 13. What will be the measure of the shorter sides? Select from the drop-down menu to correctly complete the statement. The measure of the shorter sides will be Choose... cm.


11.0813 cm

  • Determine the scale factor after reduction. SF = Original size / Reduced size. SF = 40.5cm / 13 = 3.1154.
  • Calculate the reduced length of the shorter sides. Reduced length = Original length / SF. Reduced length = 34.5cm / 3.1154 = 11.0813.
