Mary wants to hang 2 photos that are different sizes on her wall. She drew the model below to show how she will hang them.

Which one shows the correct way to calculate the area of the figure?

• 3 + 5 = 8,

  2 + 3 = 5,

  8 + 5 = 13 square units

• 3 x 5 = 15

  2 x 3 = 6

  15 + 6 = 21 square units

• 3 x 2 = 6

  6 x 5 = 30

  30 - 3 = 27 square units

• 3 + 2 = 5

  5 + 3 = 8

  5 x 8 = 40 square units
