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 in2. 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
