Based on the plan, what is the foundation slab area in square feet?

• A. 1800 sq ft
• B. 1844 sq ft
• C. 1930 sq ft
• D. 1700 sq ft

Answer: (B)

Foundation slab area is the concrete footprint shown by the exterior outline on the plan. To get it, read the plan at its scale, trace the foundation’s outer boundary, then break that irregular shape into simple pieces (usually rectangles). For each piece, multiply its length by its width to find its area, and then add all the pieces together. When you do this for the plan, the total comes out to 1844 square feet, which is why that option is correct. The other numbers would come from omitting a portion of the footprint or using the wrong dimensions for one of the pieces.
