Question

Tristan is trying to place the missing piece of a puzzle. To do so, he needs to pick the piece with the greatest perimeter.

Choose the correct piece from the options.

• A. (1)
• B. (2)
• C. (3)
• D. (4)

Answer 1

The correct option is B (2)

Let's find the perimeter of each of the above pieces.

Perimeter of figure 1: 7 + 5 + 7 + 5 = 24 in
Perimeter of figure 2: 6 + 10 + 6 + 4 = 26 in
Perimeter of figure 3: 3 + 3 + 3 + 3 = 12 in
Perimeter of figure 4: 4 + 4 + 4 + 4 + 4 = 20 in

Hence, the piece with the greatest perimeter is 2.
