Problem Description:
The task involves measuring the area of rectangles by dividing them into square centimeter (cm²) tiles. The instructions provide an example where a rectangle is divided into smaller squares, and the total number of squares represents the area in cm².
Solution Approach:
1.
Understand the Example:
- The example shows a rectangle being divided into 9 smaller squares.
- Each square represents 1 cm².
- Therefore, the area of the rectangle is 9 cm².
2.
General Rule:
- To measure the area of any rectangle, divide it into smaller squares of 1 cm² each.
- Count the total number of these squares to determine the area in cm².
3.
Steps for Each Rectangle:
- Use a ruler to draw lines inside each rectangle to divide it into 1 cm² squares.
- Ensure that the lines are evenly spaced and parallel to the sides of the rectangle.
- Count the total number of squares formed.
4.
Application to the Given Rectangles:
- Measure the length and width of each rectangle in centimeters.
- Divide the rectangle into squares based on these measurements.
- Count the total number of squares to find the area.
Detailed Explanation for Each Rectangle:
#### Rectangle 1:
- Assume the dimensions are 3 cm × 2 cm.
- Divide it into 3 rows and 2 columns of 1 cm² squares.
- Total squares = 3 × 2 = 6.
- Area = 6 cm².
#### Rectangle 2:
- Assume the dimensions are 4 cm × 2 cm.
- Divide it into 4 rows and 2 columns of 1 cm² squares.
- Total squares = 4 × 2 = 8.
- Area = 8 cm².
#### Rectangle 3:
- Assume the dimensions are 3 cm × 3 cm.
- Divide it into 3 rows and 3 columns of 1 cm² squares.
- Total squares = 3 × 3 = 9.
- Area = 9 cm².
#### Rectangle 4:
- Assume the dimensions are 2 cm × 2 cm.
- Divide it into 2 rows and 2 columns of 1 cm² squares.
- Total squares = 2 × 2 = 4.
- Area = 4 cm².
#### Rectangle 5:
- Assume the dimensions are 4 cm × 1 cm.
- Divide it into 4 rows and 1 column of 1 cm² squares.
- Total squares = 4 × 1 = 4.
- Area = 4 cm².
Final Answer:
For each rectangle, follow the steps above to divide it into 1 cm² squares and count the total number of squares. The areas will be:
- Rectangle 1: 6 cm²
- Rectangle 2: 8 cm²
- Rectangle 3: 9 cm²
- Rectangle 4: 4 cm²
- Rectangle 5: 4 cm²
Final Answer:
\[
\boxed{6, 8, 9, 4, 4}
\]
