Answer:

B. Quadrupled.

Explanation:

Let x and y be the original dimensions of a rectangle.

So, the area of rectangle will be x*y.

If we will double the dimensions of a figure, then the dimensions of new figure will be 2 times the original dimensions.


\text{Area of new rectangle}=(2x*2y}


\text{Area of new rectangle}=4xy

As the dimensions are doubled, therefore, the resulting area of the figure will be quadrupled and option B is the correct choice.
