Answer:

The [ Diagonal ] one has the largest area of [ 48√2 cm² ]

Explanation:

For behind area:

  • 12 × 4 = 48 cm²

For bottom area:

  • 4 × 12 = 48 cm²

Find the diagonal length:

  • c² = 4² + 4²
  • c = √32
  • c = 4√2

For the left sides:

  • 1/2 × 4 × 4 = 8 cm²

For the diagonal area:

  • 4√2 × 12 = 48√2 cm²  ← This is the greatest area found.
