Explanation

 
Side of Square = 5 cm, and 
length of one side of rectangle = 5/2 = 2.5 cm

Let the length of the other side of the rectangle = B

As per the question:

Area of rectangle = Area of square

Length x Breadth = Side x Side
                2.5 * B = 5 * 5
                         B = 25/2.5
                         B = 10 cm
