Answer:
20
Explanation:
Each side of the square is 5 units. The formula for area is Length times width, so its
5x5=25
but the formula for perimeter is length+width+length+width or length+width times 2
so you just add up all the side.
5+5+5+5=20
All sides are always gonna be the same size on a square so thats how we know they are all 5 units.
Hope this helped :)
