You want to create a figure with a width twice its height, and the total area of the figure should be 18 square inches. What figsize tuple should you use?
A(9, 2)
B(6, 3)
C(3, 6)
D(4, 4.5)
Step-by-Step Solution
Solution:
  1. Step 1: Define variables for width and height

    Let height = h, width = 2h.
  2. Step 2: Use area formula

    Area = width * height = 2h * h = 2h^2 = 18.
  3. Step 3: Solve for h

    2h^2 = 18 -> h^2 = 9 -> h = 3.
  4. Step 4: Calculate width

    Width = 2 * 3 = 6.
  5. Final Answer:

    (6, 3) -> Option B
  6. Quick Check:

    Width twice height and area 18 = (6, 3) [OK]
Quick Trick: Use area and ratio to find figsize tuple [OK]
Common Mistakes:
  • Swapping width and height
  • Incorrect area calculation
