Area Strategy 1 - Count up all the squares

Front

What is the formula to calculate the area of a square?

Back

Area = side × side (or Area = side²)

Front

How do you count the area in square units?

Back

Count the total number of unit squares that fit within the shape.

Front

What is the area of a square with a side length of 4 units?

Back

16 square units (4 × 4 = 16)

Front

If a square has an area of 25 square cm, what is the length of one side?

Back

5 cm (since 5 × 5 = 25)

Front

What is the relationship between area and perimeter in a square?

Back

Area measures the space inside the square, while perimeter measures the distance around it.

Front

How do you convert square units from cm² to inches²?

Back

Use the conversion factor: 1 inch = 2.54 cm, so 1 cm² = (1/2.54)² inches².

Front

What is the area of a rectangle with a length of 5 units and a width of 3 units?

Back

15 square units (Area = length × width = 5 × 3)

Front

How can you find the area of irregular shapes?

Back

Divide the shape into regular shapes (like squares and rectangles), calculate their areas, and sum them up.

Front

What is the significance of labeling units when calculating area?

Back

Labeling units (like square cm or square inches) indicates the measurement system and helps avoid confusion.

Front

If a square has an area of 36 square inches, what is the perimeter?

Back

24 inches (since the side length is 6 inches, and Perimeter = 4 × side = 4 × 6).
