Answer:
0.5
Step-by-step explanation:
First find the mean of the data
3+4+4+5 = 16
16/4 = 4
Find the distance of each data to the mean
4-3 = 1
5-4= 1
4-4 = 0
4-4 = 0
Now find the mean of those
1+1+0+0 = 2
2/4
MAD = 0.5
We know that the original width was 5, and that after the enlargement the width is 45. To calculate the scale factor we divide the final width between the original one, then:

Therefore the scale factor is 9.

For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:

Where:
p: It is the perimeter of the base
S: It's the inclination
It is the area of the base
Substituting:

ANswer:
Option B
