Which area partition in a square of side (p+q) represents the identity (p+q)^2?

Answer and explanation

Correct answer: One p² square, one q² square, and two rectangles of area pq

The direct answer is A. Divide each side of the large square into two parts, p and q. This creates four smaller regions: a p by p square with area p², a q by q square with area q², and two rectangles, each measuring p by q and therefore having area pq. Adding all four regions gives p² + pq + pq + q² = p² + 2pq + q². This is exactly the identity (p+q)². B is wrong because one pq rectangle is missing. C has the wrong shape and area, while D counts three squares and does not represent the two cross-products. Memory cue: the middle term 2pq comes from two equal pq rectangles.
