TJ is drawing an area model to find 44 x 14. What should he write in the shaded rectangle?

• 40 x 4 = 160

• 4 x 10 = 40

• 14 x 4 = 56

• 4 x 4 = 16

Look at the area model that was created to find the product of 34 and 86. Which equation can be use to find p, the product of 34 and 86?

• 2,400 + 180 + 320 - 24 = p

• 2,400 + 180 + 320 + 24 = p

• 2,400 + 180 - 320 - 24 = p

• 2,400 x 180 x 320 x 24 = p
