- AIt is too large, because the squares less than half covered should have been left out.
- BIt is too small, because he missed the fully covered squares.
- CIt is exactly right, since every square the shape touches is part of it.
- DNothing can be said unless the shape is drawn again.
Step-by-Step Solution
The rule is to count a square only when MORE than half of it lies inside the shape, and to ignore it when less than half does. By counting the less-than-half squares as well, Nikhil has added surface the shape does not actually cover, so his estimate comes out bigger than the true area.
Answer: A) It is too large, because the squares less than half covered should have been left out.
