A large square has side m, and the removed small square has side n. The remaining area is linked to which identity?

Answer and explanation

Correct answer: m²−n²=(m+n)(m−n)

The direct answer is B: m²−n²=(m+n)(m−n). The large square has area m², and removing the smaller n by n square removes area n². Therefore the remaining area is m²−n². The difference-of-squares identity says this expression can be factored as (m+n)(m−n), which can also be understood by rearranging the remaining pieces into a rectangle with those two side lengths. Option A adds the small square instead of removing it. Option B correctly states both the remaining area and its factorised form. Option C is the identity for (m+n)², where the small square and two mixed rectangles are added. Option D is (m−n)², which represents a complete square with side m−n, not simply a large square with an n² corner removed. Memory cue: removing one square from another gives a difference of squares, not the square of a difference.
