Perimeter And Area - Quiz

Math Unit 8


Questions and Answers
  • 1. 

    Understanding area and perimeter can help me to know what it will cost me to put a new floor in my home or put a fence around my yard.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Understanding area and perimeter is important because it allows me to calculate the amount of material I will need for a project such as putting a new floor in my home or installing a fence around my yard. By knowing the area, I can determine the amount of flooring or fencing material required, which in turn helps me estimate the cost of the project accurately. Therefore, the statement is true.

    Rate this question:

  • 2. 

    What is the area of the figure?             

    • A.

      4

    • B.

      8

    • C.

      2

    Correct Answer
    B. 8
    Explanation
    The area of the figure is 8 because the figure is a rectangle with a length of 4 units and a width of 2 units. To find the area of a rectangle, you multiply the length by the width, which in this case is 4 x 2 = 8.

    Rate this question:

  • 3. 

    Which number sentence represents the area of the figure?                                    

    • A.

      3 + 6 =

    • B.

      3 x 6 =

    • C.

      3 + 6 + 3 + 6 =

    Correct Answer
    B. 3 x 6 =
    Explanation
    The number sentence "3 x 6 =" represents the area of the figure because it is a multiplication equation, and the area of a figure is calculated by multiplying the length by the width. In this case, the length is 3 and the width is 6, so multiplying them together gives us the area of the figure.

    Rate this question:

  • 4. 

    Which number sentence represents the area of the figure?                     

    • A.

      2 + 4 =

    • B.

      4 + 4 =

    • C.

      4 x 2 =

    Correct Answer
    C. 4 x 2 =
    Explanation
    The number sentence 4 x 2 = represents the area of the figure.

    Rate this question:

  • 5. 

    Which number sentence represents the perimeter of the figure?                      

    • A.

      4+6+4+6 =

    • B.

      4 + 6 =

    • C.

      6 x 4 =

    Correct Answer
    A. 4+6+4+6 =
    Explanation
    The given number sentence, 4+6+4+6, represents the perimeter of the figure.

    Rate this question:

  • 6. 

    For which figure would the perimeter be solved by the number sentence 4+6+4+6?a.    b.     c.

    • A.

      Figure a

    • B.

      Figure b

    • C.

      Figure c

    Correct Answer
    C. Figure c
    Explanation
    Figure c would have a perimeter that is solved by the number sentence 4+6+4+6 because it has sides of length 4 and 6. The perimeter of a figure is the sum of the lengths of all its sides, so adding up the lengths of the sides in figure c gives us a perimeter of 20.

    Rate this question:

  • 7. 

    A rectangle has a length of 8 meters and a width of 5 meters. What is its perimeter and area?

    • A.

      Perimeter: 26 meters, Area: 40 square meters

    • B.

      Perimeter: 26 meters, Area: 30 square meters

    • C.

      Perimeter: 40 meters, Area: 26 square meters

    • D.

      Perimeter: 30 meters, Area: 40 square meters

    Correct Answer
    A. Perimeter: 26 meters, Area: 40 square meters
    Explanation
    To find the perimeter and area of a rectangle with a length of 8 meters and a width of 5 meters:
    The perimeter is calculated by adding the length and the width, then multiplying by 2. So, (8 + 5) times 2 equals 26 meters.
    The area is calculated by multiplying the length by the width. So, 8 times 5 equals 40 square meters.
    Therefore, the correct answer is: Perimeter: 26 meters, Area: 40 square meters

    Rate this question:

  • 8. 

    Which figure has an area of 5?  a.        b.      c.

    • A.

      A

    • B.

      B

    • C.

      C

    Correct Answer
    A. A
  • 9. 

    Considering a single cube is a unit, what will be the perimeter of a rectangle formed by eight such cubes?     

    • A.

      12

    • B.

      4

    • C.

      4 x 2

    Correct Answer
    A. 12
    Explanation
    If a single cube has a unit area (which means each face of the cube has a side length of 1 unit), and you arrange 8 of these cubes to form a rectangular shape, it would be a 2x2x2 cube.

    To find the perimeter of this rectangular shape, you can add up the lengths of all the edges. In this case, the perimeter would be:

    Perimeter = 2 * (length + width + height)

    Perimeter = 2 * (2 + 2 + 2)

    Perimeter = 2 * 6

    Perimeter = 12 units

    So, the perimeter of the rectangle formed by 8 such cubes would be 12 units.

    Rate this question:

  • 10. 

    Which figure has a perimeter of 16? a.      b.      c.

    • A.

      A

    • B.

      B

    • C.

      C

    Correct Answer
    B. B
    Explanation
    Figure b has a perimeter of 16 because it has four sides of equal length, each measuring 4 units. Adding the lengths of all four sides (4 + 4 + 4 + 4) gives a total perimeter of 16 units.
