8-114.
  1. is the midsegment of ΔACD , shown below. Homework Help ✎

    1. Find the perimeter of ΔACD.

    2. If the area of ΔABE is 54 cm2, what is the area of ΔACD ?

The perimeter of ΔACD = (2)(the perimeter of ΔABE).
Since BE is a midsegment, the two triangle have a zoom factor of 2, that is why it is multiplied by 2.

The area of ΔACD = (the area of ΔABE)(the zoom factor)².
