Assume the footprint is a rectangle and divide the weight (Mg) by the area of that rectangle.

2.13

• physic -

First convert the lengths from cm to m.
After that, you multiply them to find the area, and divide the weight by the area.
A=(0.13)(0.28)=0.0364
P=(75)/(0.0364)=2100 rounded
in scientific notation that equals
2.1*10^3 Pa
