The square area used in the shortcut method for a circle with a diameter of 20 feet is:

Explanation:
The shortcut method uses a square whose side equals the circle’s diameter. Its area is D squared. With a diameter of 20 feet, the square area is 20 × 20 = 400 square feet. If you wanted the circle’s actual area, it would be about π/4 of that square, which is roughly 0.785 × 400 ≈ 314 square feet.
