Let’s assume the breadth of the rectangle is x. Then, the length of the rectangle is 1.2x (20% more than the breadth).

The area of the rectangle is given by length * breadth: Area of rectangle = (1.2x) * x = 1.2x^2

The side of the square is equal to the breadth of the rectangle, so it is also x.

The area of the square is given by side * side: Area of square = x * x = x^2

The ratio of the area of the rectangle to the area of the square is: (1.2x^2) / (x^2)

Simplifying the ratio, we get: 1.2

Therefore, the ratio of the area of the rectangle to the area of the square is 1.2.
