Measuring a home with an irregular footprint requires:

Correct Answer

D) Breaking the outline into rectangles and summing them

Why this is correct: For an irregular footprint, the area is found by dividing the floor plan into measurable rectangles (or other simple shapes), calculating each area, and summing them. Why the other choices are wrong: "Multiplying perimeter by the wall height" calculates wall area, not floor area. "Using the largest single rectangle that fits the floor plan" overestimates area by including non-existent space. "Averaging the longest and shortest dimensions" is an inaccurate approximation. Exam tip: Always sketch and decompose irregular shapes; ensure the sketch 'closes' to verify all dimensions are captured.
