@lamy List the question's answers, don't randomly throw out that you think the answer is 'B' or 'C' without listing the problems and expect people to instantly know your options. So, keep that in mind.
Alright, to answer this question of yours:
The perimeter is adding all sides together, after all the perimeter is the outer ridge, not the insides, an example could be that the cops covered the perimeter of the building, that would be the outside of the building, right?
So, in terms of this let's list all of the side lengths that you have:
60 5/6, 54 1/3, 56 1/6, 59 1/3
Knowing this, we need to list them in an equation format:
60 5/6 + 54 1/3 + 56 1/6 + 59 1/3 = ?
Now we have to make the fractions even.
60 5/6 + 54 2/6 + 56 1/6 + 59 2/6 = ?
Now to finalize by adding everything together:
56 + 54 = 110
110 + 60 = 170
170 + 59 = 229
5/6 + 2/6 = 7/6 -or- 1 1/6
7/6 + 1/6 = 8/6 -or- 1 2/6 -or- 1 1/3
8/6 + 2/6 = 10/6 -or- 1 4/6 -or- 1 2/3
229 + 1 2/3 = 230 2/3
To finalize with estimation it would roughly be:
230.3 sq. ft. -or- 230 2/3 sq. ft.
Have a great day!
