What is area?
Area is the amount of space taken up/occupy/covered by a shape.
100
11 square units
100
The area of a textbook is 12 sq. inches.
Its length is 3 in. What is its width?
Width is 4 in.
100
Area is the amount of space a shape or figure takes up.
True
200
What are the units being used to measure the area of this shape?
cm
200
What are the dimensions of the rectangle below?
What is the equation that can help us calculate the area of this shape?
Remember: Each square = 1 sq. unit
Dimensions : L = 3 units, W= 5 units
Equation: A = L x W = 3 x 5= 15 sq. units
200
A rectangular door has an area of 75 sq. inches. Its width is 5 inches. What is the measurement for its length?
L= 15 in.
200
Area is measured using units.
False- It is measured using square units.
300
Why can't I find the area of a shape with gaps/or overlaps in it?
Because area is the measurement of the amount of space inside another shape/ amount of space a shape takes up so if you have gaps/overlaps you are not really doing an accurate measure.
300
a. 12 square units.
b. 30 sq. units
c. 25 sq. units
d. 20 sq. units
300
What is the measurement of the missing side?
What equation can help you find the missing side?
4 feet; 36/9
300
True or False: You would use area to determine how long a football field is?
False
Length is only one dimension. Area is calculated by taking into account the shape's length and width.
400
Can two shapes have the same area?
Give an example.
Yes. You can have a table that is 3 ft long and 6 feet wide or a table that is 9 ft long and 2 ft. Both areas are 18 sq ft.
400
Identify the dimensions, equation, and area of the following shape.
** Each square measure 1 cm.
Dimensions : L = 4 cm; W = 4 cm, Area = 4 cm x 4 cm = 16 sq cm
400
What would be half of this area?
What would be this area doubled?
Missing side: 8 sq. unit
Half: 32 sq. units
Doubled: 128 sq. units
400
True or False: You would use area to determine the amount of water in a bottle?
If false, what would you use to determine the amount of water in a bottle?
False. You will need to calculate the amount of liquid volume.

Use the following information to make two connections about the areas of the rugs below.
Provide 3 connections
Rug 1 has a length of 4 feet and a width of 9 ft.
Rug 2 has a length of 3 ft and a width of 6 ft.
Rug 1 has a larger area than Rug 2. (36 sq ft vs. 18 ft)
Both areas are being measured using sq. ft.
Rug 2 covers half the space of Rug 1 ( 18 vs 36)
Rug 1 is doubled the space of Rug 2 ( 18 vs 36)
Rug 1's length is longer by 1 ft, wider by 3 ft.
If I place the rugs next to each other, they would take up 72 sq. ft.
When I multiply an odd number by an even number, I get an even product.
500
A rug has an area of 36 sq. feet. Identify another item that can cover the same amount of space.
Remember to identify your dimensions and units.
Any item that measures 4 cm x 9 cm; 3 units x 12 units, 6 units x 6 units, 2 units x 18 units, 1 unit x 36 units,
500
A squared carpet covers up an area of 144 square feet. What are its dimensions?
L and W = 12 feet. Squares have sides that all measure the same.
500
True/False: You would use area to determine how much dirt you need for a squared garden whose width is 5 feet?
If true, what is the area of the garden?
True because the dirt is the shape inside the garden.
Squares have sides that all measure the same so its area is 5 ft x 5 ft= 25 ft.
