Which of the following can visually let you know the square units of a square?

• A.

Count all the square units that you can see in the square.

• B.

By counting the squares in the right and left side.

• C.

You can count some of the square units

• D.

Through counting one side vertically and one side horizontally

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

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:

• 4.

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.

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.

How many square units does this square have?

• A.

20

• B.

25

• C.

26

• D.

22

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.

• 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

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:

• 8.

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.

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?

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.

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

• A.

12

• B.

16

• C.

24

• D.

32

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

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.

• B.

410 sq. m.

• C.

450 sq. m.

• D.

430 sq. m.

C. 450 sq. m.
Explanation
The area of a rectangle can be found by multiplying its length by its width. In this case, the length of the land is given as 30 m and the width is given as 15 m. Therefore, the area of the land can be calculated as 30 m * 15 m = 450 sq. m.

• B.

Area = 48

• C.

Area = 40

• D.

Area = 32

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.

• D.

6 m. 2

B. 4m. 2
Explanation
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 given as 2m. Therefore, the area of the square table would be 2m multiplied by 2m, which equals 4m².

Rate this question:

• 17.

Mr. Cruz has a garden on his backyard. Its area is 10 square units. Which of the following can show the area of his garden when the square units are drawn?

C.
Explanation
The correct answer is a square with side length of 10 units. This is because the area of a square is calculated by multiplying the length of its sides, so a square with side length of 10 units would have an area of 10 square units.

The area of the park is 200 sq. units.  If the width is 10 units, what is the length?

• A.

30 units

• B.

10 units

• C.

20 units

• D.

40 units

C. 20 units
Explanation
Since the area of the park is given as 200 sq. units and the width is given as 10 units, we can use the formula for the area of a rectangle (Area = Length x Width) to find the length. Rearranging the formula, we have Length = Area / Width. Substituting the given values, we get Length = 200 / 10 = 20 units. Therefore, the length of the park is 20 units.

Rate this question:

• 20.

Lara's vegetable garden is 20 sq. m. Her neighbor, Catherine; has a vegetable garden next to her that is 33s. q m. The two neighbors decided to join the two gardens, what is the area of both vegetable gardens when combined?
