Answer:
Following are the responses to the given question:
Step-by-step explanation:
Mean Absolute Deviation MAD
Mean squared error
linear trend equation is ![Ft = 124 + 2t](https://tex.z-dn.net/?f=Ft%20%3D%20124%20%2B%202t)
![MAD = \frac{23}{10} = 2.3\\\\MSE = \frac{91}{9}= 10.11\\\\](https://tex.z-dn.net/?f=MAD%20%3D%20%5Cfrac%7B23%7D%7B10%7D%20%3D%202.3%5C%5C%5C%5CMSE%20%3D%20%5Cfrac%7B91%7D%7B9%7D%3D%2010.11%5C%5C%5C%5C)

<h3>
Answer: D) 144 square cm</h3>
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.
---------
Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
