Answer:

  1. 3.04 m
  2. 18

Step-by-step explanation:

The midsegment of a triangle is half the length of the side it is parallel to.

1. For a distance of 6.08 m between wall plates, the colar tie will be half that, or 3.04 m.

2. The perimeter of ΔXYZ is ...

... 10 + 12 + 14 = 36

The sides of ΔABC are half the length of the sides of ΔXYZ, so the perimeter of ΔABC is half the perimeter of ΔXYZ.

... perimeter of ΔABC = 36/2 = 18
