Describe in words how to find the area of a square. What if the side length is s?

Multiple Choice

Write a multiplication expression using the side length s

• s

• 2*s

• 3s

• s*s

Multiple Choice

How can we write s*s in exponential form?

• 2*s

• 2s

• s²

• s

So, now we know the following

• s*s=s¹⁺¹=s²

• The area of a square is equal to the side length squared

• A=s²

• Area is the amount of space inside

So, now that we know
A=s2
A=49
Then s2=49, so we take the square root

 $\sqrt{s^2}=\sqrt{49}$ 
s=7
