Answer 2

Drawing the Rectangle

To draw a rectangle ABCD in your notebook, with a length of 1 dm and 2 cm, and a width of 5 cm, follow these steps:

1. Start by drawing a horizontal line segment AB with a length of 1 dm and 2 cm (12 cm + 2 cm = 14 cm). 2. From point B, draw a vertical line segment BC with a length of 5 cm. 3. Connect points C and D with a horizontal line segment CD, parallel to AB. 4. Finally, connect points D and A with a vertical line segment AD, parallel to BC.

Your rectangle ABCD should now be drawn in your notebook.

Measuring the Lengths of AC and BD

To measure the lengths of AC and BD, use a ruler or a measuring tape. Place the ruler or measuring tape along each line segment and read the measurements.

1. Measure the length of line segment AC. This will give you the length of one diagonal of the rectangle. 2. Measure the length of line segment BD. This will give you the length of the other diagonal of the rectangle.

Observations

Based on the measurements, you can make the following observations:

1. The length of line segment AC is equal to the length of line segment BD. 2. The diagonals of a rectangle are always equal in length. 3. In this case, the diagonals AC and BD are equal because the rectangle is a rectangle by definition.

I hope this helps! Let me know if you have any further questions.
