There is no lack of parameters, area movement operation is not difficult!

What is the formula for finding the length of a square?
My fifth grade primary school, the best text easy to understand

Square area = square side length × square side length
Square side length = √ square area (√ means root)
If the square area is 9, the square side length = √ 9 = 3

Given the area of a square, what is the formula for finding the side length
Who did the answer of this problem will give 50 reward! Title: the area of a square is 5 square centimeters. If you draw a circle with a vertex of the square as the center and the side length of the square as the radius, how many square centimeters is the area of the circle?

Square root of area
