# Lesson Worksheet: Areas of Rectangles with the Same Perimeter Mathematics • 3rd Grade

In this worksheet, we will practice drawing rectangles with the same perimeter, counting unit squares to find their areas, and comparing these areas.

**Q1: **

True or False: The two given rectangles are equal in perimeter and equal in area.

- ATrue
- BFalse

**Q2: **

Rectangle A and rectangle B have the same perimeter. Which of them has a larger area?

- ARectangle A
- BRectangle B

**Q3: **

True or False: The two given rectangles are equal in perimeter but not equal in area.

- ATrue
- BFalse

**Q4: **

Which of the following rectangles has the same perimeter as but a larger area than the given rectangle?

- A
- B
- C
- D

**Q5: **

Rectangle A and rectangle B have the same perimeter. Which of them has a smaller area?

- ARectangle B
- BRectangle A

**Q6: **

Which of the following rectangles has the same perimeter as but a smaller area than the given rectangle?

- A
- B
- C
- D

**Q7: **

Look at rectangles A and B.

The area of Rectangle A is 32 in^{2}.
Mason says that the area of Rectangle B must be different because their perimeters are different.
Find the area of Rectangle B to check if Mason is correct.

**Q8: **

Which two rectangles have the same perimeter?

- AB and D
- BA and D
- CA and C
- DB and C

Which rectangle has the smallest area?

- AC
- BA
- CD
- DB

**Q9: **

These three rectangles have the same perimeter. Which one has the greatest area?

- AA
- BB
- CC

**Q10: **

These three rectangles have the same perimeter. Which one has the smallest area?

- AB
- BA
- CC
