In the visual model of the square of a+b, into which parts is the large square divided?

Advertisement

Answer and explanation

Correct answer: एक a² वर्ग, एक b² वर्ग और ab क्षेत्रफल वाले दो आयत

The large square has side a+b. Splitting each side into a and b gives one a² square, one b² square, and two ab rectangles, so its area is a²+2ab+b². In exams, remember to count both middle ab regions.
