Exercise:  Find the area of all the shapes for all the questions.  Choose the correct working and answer.

• A = 3 + 3
  = 6 cm

• A = 3 x 3

  = 6 cm²

• A = 3 x 3
  = 9 cm²

• A = 10 x 3

  = 30cm²

• A = 10 + 3

  = 30cm²

• A = 10 + 3

  = 13cm²

• A = 5 + 8

  = 13 cm²

• A = 8 + 5

  = 13 cm²

• A = 8 x 5

  = 40cm²

• A = 7 + 7

  = 49cm

• A = 7 x 7

  = 49cm

• A = 7 x 7

  = 49cm²
