Answer:
- 3.04 m
- 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
