Answer:
2 posts
Step-by-step explanation:
Bob is going to build a deck that is 7 feet long and he is going to use posts that are 6 inches wide = 0.5 feet wide.
He is going to put the posts 6 feet apart and one on each end.
So the first thing will be a post 0.5 feet, and after 6 feet another post of another 0.5 feet, so if we add all of this will be:
0.5 feet + 6 feet + 0.5 feet = 7 feet
So he will only use 2 posts.

Answer:
- perimeter: 56 units
- area: 192 square units
Step-by-step explanation:
We assume you're interested in the convex polygon, so the given vertices are <em>not</em> listed in order around the figure.
The figure is 12 units by 16 units, so has a perimeter of ...
P = 2(L +W)
P = 2(16 +12) = 56 . . . . units
and an area of ...
A = LW
A = (16)(12) = 192 . . . . square units
