Question

If there are 2 squares and 2 rectangles, how many right angles are there?

• A. 4 right angles
• B. 16 right angles
• C. 12 right angles
• D. 8 right angles

Answer 1

The correct option is B 16 right angles

• Let us observe the 2 shapes, the square, and the rectangle.

• 1 square has 4 right angles.
• 2 squares have:
  2 × 4 right angles = 8 right angles
• Similarly, 1 rectangle has 4 right angles.
• 2 rectangles have:
  2 × 4 right angles = 8 right angles
• 2 squares + 2 rectangles = 8 + 8 = 16 right angles

Hence, option D is the correct answer.
