Answer:

20y

Step-by-step explanation:

Area of rectangle = area of square

=> length * breadth = side²

=> 50y * 8y = side²

=> 400y² = side²

=> (20y)² = side²

=> 20y = side length of square
Let k be the side length of the square.
Since the area of the rectangle and the square is equal,
8yx50y=k^2
Or,400y^2=k^2
or,k=20y
