Estimate to draw three different rectangles with a perimeter of 16 centimeters. Label the width and length of each rectangle. Explanation:
Using the Perimeter of 16 cm we can draw three rectangles ABCD, EFGH, IJKL with different lengths and width.

### Eureka Math Grade 3 Module 7 Lesson 24 Homework Answer Key

Question 1.
Brian draws a square with a perimeter of 24 inches. What is the length of the side of the square?
Length of the side of the square = 6 inches.

Explanation:
Perimeter of the Square = 24 inches
Number of sides in the square = 4
Length of the side of the square = Perimeter of the Square  ÷ Number of sides in the square
= 24 inches ÷ 4
= 6 inches.

Question 2.
A rectangle has a perimeter of 18 centimeters.
a. Estimate to draw as many different rectangles as you can that have a perimeter of 18 centimeters. Label the width and length of each rectangle.
b. How many different rectangles did you find?
c. Explain the strategy you used to find the rectangles.
a. b. I could find three different rectangles having perimeter as 18 centimeters.

c. The strategy which I used to find the rectangles is that :
Step 1:  Considered the Perimeter formula 2 ( Length + Width ) and its perimeter value 18 centimeters.
Step 2: Calculated the Length and width values.
Step 3: Keeping in mind highest value as length and lesser as Width.
