The answer you are looking for is 49 cm².
Solution/Explanation:
Writing out the formula for the area of a square
A=s²
By the way, "s" means the same thing as side.
If the side length is 7, this means that s=7.
Substituting the given value of the variable
A=7²
7² or 7×7=49.
You will get A=49.
Or, even better, A=49 cm².
Also, by the way, "A" is the same thing as area.
So, therefore, the final answer to this problem is A=49 cm².
Hope this helped answer your question for you. Good day to you.
