The answer is 100 Pa.
The formula for calculating pressure is :
<u>Pressure = Force ÷ Area</u>
<u />
We are given that :
We also know that :
<u>Force = mass ×g</u>
<u />
So, force will be :
Now, we can finally calculate pressure :
Well the width is 0.20 meters. Since there are a hundred centimeters in a meter, we just have to move the decimal point two times to the right to get a 20 centimeter width.
