This is a good example of unit conversion. Look at the units you have and the units you need to solve for.
In #1 you’re given weight in units N and area in units cm². You want to find pressure in units Pa (pascals) which is force/area, or N/m². So you just divide the force given by the area given, but be careful because the area is given in cm², whereas pressure is in m². Before you calculate pressure, make sure you convert 324cm² into m²
