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

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
