A press applies a normal force of 6000 N to a sheet using a rectangular platen. The platen is then replaced by a different one, and the press applies the same force. The table gives the dimensions of each platen.
| Platen | Length in cm | Width in cm |
|---|---|---|
| First | 20 | 15 |
| Replacement | 20 | 7.5 |
Calculate the pressure exerted by the first platen on the sheet.
Explain how the pressure exerted by the replacement platen compares with the pressure exerted by the first platen.
