10 4/6

John was building a new fence, and he wants it to stand 8 ½ feet above ground level. To make sure it is secure he must place it 2 ¾ feet into the ground. How long of a post should John buy?

To determine the length of the post that John should buy, we need to combine the height above ground and the depth into the ground.

The height above ground is given as 8 1/2 feet and the depth into the ground is given as 2 3/4 feet.

To add these two measurements together, we need to make sure that the units of measurement are the same. In this case, they are both in feet, so we can directly add them.

8 1/2 feet + 2 3/4 feet = 11 1/4 feet

Therefore, John should buy a post that is 11 1/4 feet long.
