Answer:

Pressure, P = 7 Pa

Explanation:

Given that,

Force exerted on the surface, F = 42 N

Length, l = 3 m

Width, b = 2 m

We need to find the pressure exerted by this force. We know that, pressure is equal to force per unit area. So,

[tex]P=\dfrac{F}{l\times b}\\\\P=\dfrac{42}{3\times 2}\\\\P=7\ Pa[/tex]

So, the required pressure is equal to 7 Pa.
