The perimeter is the sum of all side lengths of a given shape, and can be computed by adding up all of the side lengths.
So in this case, it would be 15 x 2 + 13 x 2 the sum of them would be equal to the perimeter of the object, I believe.
Answer:
what are the given values?
1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =
7 + 2 + 9 + 8 + 10 =
36
Now we need to divide 36 by the total frequency: 7+1+3+2+2=15
36 / 15 = 2.4
The distribution is skewed to the right
