BA/tree (sq ft) is expressed in what unit?

BA/tree (sq ft) is expressed in what unit?

• A. Cubic feet
• B. Square meters
• C. Acres
• D. Square feet

Answer: (D)

Basal area per tree is an area measure of the trunk’s cross-section at breast height. Since area is measured in square units, the unit used here is square feet. Basal area is computed as π × (DBH/2)², and if DBH is in inches you’d get square inches; converting to square feet makes this a square-foot value. The other options represent length (cubic feet is volume, not area) or larger/switch units (acres, square meters) that don’t describe a cross-sectional area in this context.
