Which of the following is a unit of land measurement?

A front foot is a unit of land measurement that refers to the number of feet of property that borders a street or a body of water. This measurement is typically utilized in real estate and land assessments to determine the value and characteristics of a property, especially in analyzing commercial or residential lots. Front foot measurements can help assessors calculate property taxes and evaluate property values based on the land's dimensions and its location relative to access points.

The other options do not represent land measurement units; general revenue refers to government income from various sources, utilities relate to services such as water and electricity, and trust pertains to legal arrangements or entities for managing property on behalf of another. These terms are relevant in different contexts but do not serve as measurements of land.
