Answer:

4kPa

Explanation:

P = force/area

= 400/(0.5×0.2)

= 4000Pa(4kPa)

Answer:

4000pascal

Explanation:preassure = force/area

F = 400N

A = 50cmx 20cm = 1000 cm sq

so we have to convert the area in metre square

so when convert we get the answer 1/10 = 0.1m square

now as per the equation of preassure we have to divide 0.1/400

and then we get the answer 4000pascal.
