What is the pressure now?
What is the pressure new pressure?
You can see the results in the table. What happens to the pressure as the area gets bigger?
The pressure gets smaller as the area gets bigger. This is because area is on the bottom of the fraction.
In fact, when the area doubles, the pressure halves. And when the area quadruples, the pressure is quartered. The pressure goes down in the same proportion that the area goes up. We say that the pressure is inversely proportional to the area.
