<u>Solving</u>
Knowing that we have the information needed we will first find the perimeter of the rectangle. 
Rectangle:
Length: 13cm
Width: 7cm  
Formula: L+L+W+W
13+13+7+7 = 40cm
Meaning the perimeter is 40cm and we can use this to find the length of a square. From general knowledge we know that all sides of a square is equal. 
So if we divide the 4 sides by 40 we will get our answer.
40 ÷ 4 = 10
So B would be our answer...
<u>Statement</u>
<u />
Therefore the length of a side of the square is 10cm, meaning answer B is correct.

Answer:
1) a <u><</u> -8 or a <u>></u> 8
2) n = -18 or n = 18
3) z = - 1/2 or z = 1/2

The answer would most likely be reflection
        
             
        
        
        
there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
<h3>
Which expression could represent the length of the rectangle?</h3>
Remember that for a rectangle of length L and width W, the area is given by:
A = L*W
In this case, we know that the area is:

We can factorize that expression into:

So there are two expressions that can represent the length of the rectangle, these two expressions are:
L = x
or
L = (4x + 12)
