The formula for MAD is attached in the picture.
x_i are the values (data)
x bar is the mean
n is the number of numbers (data)
For figuring out MAD, basically, <em>we subtract the mean from each of the values respectively and take the absolute value and SUM for all of the numbers in the data set. Then we divide by n, the number of numbers.</em>

Let's do this:
MAD =
MAD is 0.8

Step-by-step explanation:
to find the surface area we need to find the followng areas:
- area of the square
- area of a triangle and multiply it by 4 (because there are 4 triangles)
And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:
where is the length of the side:
thus the area of the square is:
Area of the triangles:
the are of 1 triangle is given by
where is the base of the triangle:
(the base of the triangle is the side of the square)
and is the height of the triangle:
thus, the area of 1 triangle is:
the area of the 4 triangles is (we multiply by 4):
finally we add the area of the square and the area of the 4 triangles to find the total surface area:
