In a square with side 3x + 2, what is the area of the small corner?

Answer and explanation

Correct answer: 4

The direct answer is option C: 4. Split the side 3x + 2 into two parts, 3x and 2, in both directions. The square then contains a large square of area (3x)² = 9x², two rectangles each of area (3x)(2) = 6x, and one small corner square with side 2. Its area is 2² = 4. Option A, 3x, represents a length part, not an area. Option B, 6x, is the area of one of the two rectangular strips. Option C is correct because the small corner has side 2 and area 4. Option D, 9x², is the area of the large square formed by the 3x portions. The whole square has area (3x + 2)², but the question asks for only one component. Memory cue: the constant part of a square-side expression forms the corner square, so square that constant.
