    Correct Answer
    A. Count all the square units that you can see in the square.
    Explanation
    The correct answer is "Count all the square units that you can see in the square." This answer suggests that to determine the square units of a square visually, one should count all the square units that are visible within the square. This means counting the individual squares that make up the square shape. By doing so, one can determine the total area or square units of the square.

    Rate this question:

  • 3. 

    Which of the following tells how to get the area of a rectangle and a square?

    • A.

      Area     = L + W               Area    = L + W

    • B.

        Area       = L x W            Area    = S x S          

    • C.

      Area    = 2L x 2 W              Area   =  2L+2W

    • D.

      Area   =   L  ÷ W                 Area      =   L  ÷  W

    Correct Answer
    B.   Area       = L x W            Area    = S x S          
    Explanation
    The correct answer is "Area = L x W" for both the rectangle and the square. This formula calculates the area by multiplying the length (L) of the shape by its width (W). For a rectangle, the length and width can be different, while for a square, the length and width are equal (S x S).

    Rate this question:

    How do we solve problems with the area of a rectangle?

    • A.

      Add the length and the width. If the length is unknown, multiply it twice.

    • B.

      Multiply the width by itself. If the length is unknown, add the area to the width.

    • C.

      Multiply the length and the width. Divide the area to the length or the width if one                             of it is unknown.

    • D.

      Divide the area with the length or width to get the missing side of the area.

    Correct Answer
    C. Multiply the length and the width. Divide the area to the length or the width if one                             of it is unknown.
    Explanation
    To solve problems with the area of a rectangle, you need to multiply the length and the width. If either the length or the width is unknown, you can divide the area by the known side to find the missing side.

    • C.

      26

    • D.

      22

    Correct Answer
    B. 25
    Explanation
    The square in question has 25 square units. This is because the area of a square is calculated by multiplying the length of one side by itself. In this case, the length of one side is 5 units (since the square root of 25 is 5), so when we multiply 5 by 5, we get the area of 25 square units.

    Rate this question:

  • 7. 

    Which of the figures show how to get the area of a square and a rectangle?

    • A.

                  3+3=6                                   2+4=6

    • B.

                 4+4=8                                         2+2=4

    • C.

      5+5+5+5=20                         3+2+3+2= 10

    • D.

               3 x 3 =9                                                    4 x 3 = 12 

    Correct Answer
    D.          3 x 3 =9                                                    4 x 3 = 12 
    Explanation
    The figures that show how to get the area of a square and a rectangle are the ones that have the multiplication equations written on them. In this case, the figure with "3 x 3 = 9" represents the area of a square with side length 3, and the figure with "4 x 3 = 12" represents the area of a rectangle with length 4 and width 3.

    Rate this question:

    If Timmy wants to get the area of a square, which of the following can let him get  the answer?

    • A.

      Timmy can multiply one side of the square four times to get it’s area.

    • B.

      To have the area, he can add all the sides of the square.

    • C.

      Timmy must multiply one side of the square twice to have the area of a square.

    • D.

      He can add the length and width of the square to get the answer.

    Correct Answer
    C. Timmy must multiply one side of the square twice to have the area of a square.
    Explanation
    Timmy must multiply one side of the square twice to have the area of a square. This is because the area of a square is found by multiplying the length of one side by itself, or squaring it. Adding the sides or multiplying one side four times will not give the correct answer for the area of a square.

    Rate this question:

  • 9. 

    The area of the rectangle is 12 units; the length is 6. Which shows the area correctly?

    Correct Answer
    C.
    Explanation
    The area of a rectangle is calculated by multiplying its length and width. In this case, the length is given as 6 units. To find the width, we can divide the area by the length. So, if the area is 12 units, dividing it by the length of 6 units gives us a width of 2 units. Therefore, the correct answer would be the option that shows the length as 6 units and the width as 2 units, resulting in an area of 12 units.

    Rate this question:

  • 10. 

    If the side of a square table is 4 units what is the area?

    • A.

      12

    • B.

      16

    • C.

      24

    • D.

      32

    Correct Answer
    B. 16
    Explanation
    The area of a square is calculated by multiplying the length of one side by itself. In this case, the side of the square table is given as 4 units. Therefore, the area of the square table can be found by multiplying 4 by 4, which equals 16.

    Rate this question:

  • 11. 

    What is the area of the square and rectangle?

    • A.

      16 cm.2 and 24 cm.2

    • B.

      12 cm.2 and 10 cm.2

    • C.

      24 cm.2 and 16 cm.2

    • D.

      10 cm.2 and 12cm.2

    Correct Answer
    A. 16 cm.2 and 24 cm.2
    Explanation
    The area of a square is calculated by multiplying the length of one side by itself. Therefore, if the area of the square is 16 cm^2, it means that the length of one side of the square is 4 cm (since 4 * 4 = 16).

    The area of a rectangle is calculated by multiplying the length by the width. Therefore, if the area of the rectangle is 24 cm^2, it means that the length multiplied by the width equals 24. Since the question does not provide information about the dimensions of the rectangle, we cannot determine the exact values for the length and width.

    • A.

       Area = 64

    • B.

      Area = 48

    • C.

      Area = 40

    • D.

      Area = 32

    Correct Answer
    A.  Area = 64
    Explanation
    The correct answer is "Area = 64" because the formula to calculate the area of a square is side length squared. In this case, the side length of the handkerchief is given as 8 units. When we square 8, we get 64, which represents the area of the handkerchief.
