Answer 1

Givens

• The cakje is square-shaped.
• Annie is expecting 18 guests.
• Each cut is gonna be a square-shaped 2 inches long.
• Each guest must get 2 pieces each.

So, if she expects 18 guets, and she wants to give 2 pieces to each of them, that means she needs 36 cake pieces.

If each piece is 2 inches long, that means the area per piece is 4 square inches.

Therefore, she needs 144 square inches of cake to give 2 pieces to each guest and have 18 guests.

In terms of length, it would be 72 inches.
