C is the only one greater than 12.5 i think so
also b and d
For this case we have that by definition, the area of a square is given by:

Where:
l: It's the side of the square
We have, according to the statement data, that:

Then, the area is given by:

By definition of power properties we have to:

So:

Answer:
The area of the square is: 
Given:
The value of the solid's surface area is equal to the value of the solid's volume.
Length(l) = 9 units
width(b) = 4 units
Height(h) = x units
To find:
The value of x.
Solution:
Solid's surface area is





Volume of solid is



Solid's surface area = Volume of solid



Divide both sides by 10.

Therefore, the value of x is 7.2.
1/2 and 3/8
equivalent
1/2 = 4/8
so 4/8 is greater than 3/8
Answer
5 1/2 is bigger than 5 3/8
The area of the square whose sides is s inches long will be given by:
Area=length×width
Length=s inches
width=s inches
thus:
the area of the squares will be:
Area=s×s=s² sq. inches
Thus the correct answer is:
area=s² sq. in
