Answer:
5cm
Step-by-step explanation:
- In order to find the area of a 2d regular shape such as a square, you need to do length × width = area
- A square has four regular sides, which means they must all be the same length, which in turn means that we only need to find one number, and it must be the square root of 25.
So, the length of each side is 5cm.
