If your site has only four dimensions, you can enter each side's length in the Front/Left/Rear/Right fields, and the Area and Dimensions field will automatically fill out for you.
If your site is irregular, you can simply ignore the Front/Left/Rear/Right fields and manually enter your Area and Dimensions in the fields below. There are no UAD requirements concerning the Dimensions field; it is a freeform field where you can enter whatever you feel is necessary (i.e. "Irregular", "See Plat Map", a list of the dimensions, etc).
