The area of a square is 144 cm^2. The measurement of each side is 12 cm
<u>Solution:</u>
Given, The area of a square is 144 
We have to find that what is the measurement of each side.
Now, we know that, area of a square = product of side value with another side value.
Let the side value of given square be "s"
Then, <em>Area of square is given as:</em>

On cancelling square root and square on right side,we get
s = 12
Hence, the side value of the square is 12 cm.
Im guessing the first answer
The
4th selection is appropriate:
The first line is a dashed line which joins ordered pairs (-2, 1) and (3, 1). The second line is a dashed line and joins ordered pairs (-2, -2) and (3, 3). The portion common above the first line and above the second line is shaded
