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. 

    Why might you want to measure the area?

    • A.

      To know how much it will cost me to put carpet in my home

    • B.

      To know how much grass seed I need for my yard

    • C.

      All of the above

    • D.

      None of the above

    Correct Answer
    C. All of the above
    Explanation
    Measuring the area is important in order to determine the quantity of materials needed for a specific task. In the first scenario, measuring the area helps in calculating the cost of carpet required to cover the entire home. Similarly, in the second scenario, measuring the area allows for determining the amount of grass seed needed to cover the yard. Therefore, both options are valid reasons for wanting to measure the area, making the answer "All of the above" correct.

    Rate this question:

  • 3. 

    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:

  • 4. 

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

    • A.

      A

    • B.

      B

    • C.

      C

    Correct Answer
    A. A
    Explanation
    Based on the given options, figure a is the only one that has an area of 5.

    Rate this question:

  • 5. 

    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:

  • 6. 

    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:

  • 7. 

    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:

  • 8. 

    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:

  • 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.
