Answer:
P = 4000 [Pa]
Explanation:
Pressure is defined as the relationship between Force and the area where the body rests.
The support area is equal to:
[tex]A=50*20=1000[cm^{2} ][/tex]
But we must convert from square centimeters to square meters.
[tex]1000[cm^{2}]*\frac{1^{2}m^{2} }{100^{2}m^{2} }=0.1[m^{2} ][/tex]
And the pressure is:
[tex]P=\frac{F}{A} \\P=400/0.1\\P=4000[N/m^{2} ]or 4000[Pa][/tex]
