Which of the following is about 3 meters long?

Height of a table
The length of a car
From the floor to the door knob
A fence around the playground

Three meters is a little over 9 feet. What do you think?

and don't forget the word 'long' (in contrast to high or wide)

the lenght of a car???

To determine which of the following options is about 3 meters long, we need to compare the given measurements to 3 meters.

1. Height of a table: To measure the height of a table, you would need a measuring tape or ruler. Place one end of the measuring device on the ground and extend it vertically until you reach the top surface of the table. If the measured height is close to 3 meters, then the height of the table would be the answer.

2. Length of a car: Measuring the length of a car would also require a measuring tape or ruler. Position the measuring device parallel to the car and measure from the front bumper to the rear bumper. If the measured length is around 3 meters, then the length of the car would be the answer.

3. From the floor to the doorknob: Similarly, measuring the distance from the floor to the doorknob involves using a measuring tape or ruler. Place the measuring device vertically on the ground and measure up to the height of the doorknob. If the measured distance is approximately 3 meters, then "from the floor to the doorknob" would be the answer.

4. A fence around the playground: To measure the length of a fence, you would need a measuring tape or measuring wheel. Walk along the fence while unrolling the measuring tape or using the measuring wheel to determine the total length. If the measured length is close to 3 meters, then "a fence around the playground" would be the answer.

By following these measurement techniques, you can determine which option is approximately 3 meters long.
