Answer:
If the force of the explosion was focused onto a smaller area of the window, then the pressure of the explosion on the window would be even greater.
Step-by-step explanation:
Pressure is defined as force per unit area. Mathematically:

F: force
A: area
We can note that pressure and area are inversely proportional. It means that for the same force applied in a smaller area, the pressure is greater.
Let's suppose we have a force of 100N applied in an area of 2m²


For a smaller area (let's say 1m²)

the pressure is greater
The answer is: area
