In the visual model of a square of side a+b formed using parts of lengths a and b, which statement is correct?
Answer and explanation
Correct answer: The square is divided into four parts: one a² square, one b² square, and two ab rectangles
Dividing a square of side a+b at lengths a and b gives squares of areas a² and b². The remaining two regions are ab rectangles, so the area is a²+2ab+b². Exam tip: always count both ab rectangles.
