Eureka Math Grade 4 Module 3 Lesson 36 Problem Set Answer Key

Question 1.
a. In each of the two models pictured below, write the expressions that determine the area of each of the four smaller rectangles.

Answer:

Explanation:
In each of the two models pictured above, wrote the expressions that determine the area of each of the four smaller rectangles as shown above.

b. Using the distributive property, rewrite the area of the large rectangle as the sum of the areas of the four smaller rectangles. Express first in number form, and then read in unit form.
14 × 12 = (4 × __2___ ) + (4 × __10___ ) + (10 × _2____ ) + (10 × _10____ )
Answer:
14 X 12 = (4 X 2) + (4 X 10) + (10 X 2) + (10 X 10),

Explanation:
Using the distributive property, rewrote the area of the large rectangle as the sum of the areas of the four smaller rectangles.
Expressed first in number form, and then read in unit form as
14 X 12 = (4 X 2) + (4 X 10) + (10 X 2) + (10 X 10).
