1. **Problem Statement:** Calculate the site clearance measurement for the substructure of a warehouse based on the given foundation plan dimensions. 2. **Given Data:** - Outer rectangle dimensions: width = 50.00 units, height = 30.00 units - The site clearance area corresponds to the entire outer rectangle. 3. **Formula Used:** Site clearance area = width \times height 4. **Calculation:** $$\text{Site clearance area} = 50.00 \times 30.00$$ $$= 1500.00$$ 5. **Explanation:** The site clearance involves clearing the entire area of the warehouse foundation footprint, which is a rectangle with the given width and height. Multiplying these gives the total area to be cleared. 6. **Final Answer:** The site clearance measurement is **1500.00 square units**.
