Answer:
Option D. 8 units
Step-by-step explanation:
step 1
Find the area of rectangle
The area of rectangle is
![A=(4)(16)=64\ units^2](https://tex.z-dn.net/?f=A%3D%284%29%2816%29%3D64%5C%20units%5E2)
step 2
Find the length side of the square with the same area of rectangle
The area of a square is
![A=b^2](https://tex.z-dn.net/?f=A%3Db%5E2)
where
b is the length side of the square
we have
![A=64\ units^2](https://tex.z-dn.net/?f=A%3D64%5C%20units%5E2)
substitute
![64=b^2](https://tex.z-dn.net/?f=64%3Db%5E2)
take the square root both sides
![b=8\ units](https://tex.z-dn.net/?f=b%3D8%5C%20units)
therefore
The length side of the square is 8 units
