<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.
Answer:
AC = 6 ÷ 7
x = 2
Step-by-step explanation:
Given that
AB = 5x - 2
BC = 9x - 10
So,
AC = AB + BC
= 5x - 2 + 9x - 10
14x -12 = 0
AC = 6 ÷ 7
As B is the mid point of point A and point C, so the value of x is determined by solving the given equations mentioned in the question
5x - 2 = 9x - 10
5x - 9x = -10 +2
-4x = -8
x = 2
Hence, the value of AC and the X is 6 ÷ 7 and 2 respectively
