Answer: $A_2=\frac{\pi(2D)^{2}}{4}$

Step-by-step explanation:

1. You have the following formula for calculate the area of the original circular chip:

$A_1=\frac{\pi(D)^{2}}{4}$

Where D is the diameter of the circle.

2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:

$A_2=\frac{\pi(2D)^{2}}{4}$
