Answer:
The area is the side lengths squared or multiplied by themselves. The three squares have very different areas based on their side lengths. I disagree that a square with 13 inch side length will have area 13. It will have area 13*13=169 square inches.
Step-by-step explanation:
The area of a square is A=s*s.
1st: A = 1*1 = 1 square inches.
2nd: A=1/2*1/2 = 1/4 square inches
3rd: A =2*2 = 4 square inches.
The area of a square with 1 unit side length is still 1. But a square whose side is less than 1 has a very small area and the square whose side length is greater than 1 has a much larger area. The area of a square is the square of its side length or its side length times itself.
Knowing this, a square with side length 13 will not have area 13 but area 169.
