McGraw-Hill Math Grade 3 Answer Key Chapter 12 Lesson 4 Using Area Models to Represent Distributive Property
Solve
Look at the area model. Look at the multiplication sentences and choose the one that is correct. Write the correct sentence on the line.
Question 1.
4 × (4 + 4) = 32 square units
8 × (4 + 4) = 32 square units
4 × (4 + 5) = 32 square units
Answer:
4 × (4 + 4) = 32 square units
Question 2.
3 × (3 + 4) = 18 square units
3 × (2 + 4) = 18 square units
6 × (3 + 1) = 18 square units
Answer:
3 x (2 + 4) = 18 square units
Explanation:
There are 3 columns of squares with 2 rows of different color and 4 rows of different color
So, the multiplication sentence that tells about the area of the model is 3 x (2 + 4) = 18
The area of the above area model is 18 square units.
