The area of a rectangle is calculated by multiplying its length by its width. Therefore, the area of a rectangle that is 40 meters by 20 meters is 800 square meters. **

The phrase "After 100 meters" implies that something will happen once a distance of 100 meters has been covered. On the other hand, "After 100 meters?" suggests a question about what will happen after 100 meters. The first phrase is a statement, while the second is an inquiry seeking clarification or information. **

10 cubic meters is equivalent to 10,000 liters or 10,000,000 cubic centimeters. In terms of length, 10 cubic meters would be equivalent to a cube with each side measuring 2.15 meters. **

Current meters are instruments used to measure the flow of electric current in a circuit, typically measured in amperes. They are connected in series with the circuit and provide a reading of the amount of current passing through. Voltage meters, on the other hand, measure the electrical potential difference between two points in a circuit, typically measured in volts. They are connected in parallel with the circuit and provide a reading of the voltage across the points. Both current meters and voltage meters are essential tools for monitoring and troubleshooting electrical circuits. **

It was 800 meters. **

60 running meters is equivalent to 60 meters. Running meters are a unit of measurement used in the textile industry to measure the length of fabric, and in this context, 60 running meters would simply be 60 meters in length. **

12 square meters is a measure of area, not length. Therefore, it does not directly convert to a specific number of meters. However, if you are looking for the length of a square with an area of 12 square meters, you would need to calculate the square root of 12, which is approximately 3.46 meters. **

5 square meters is equivalent to 5 meters by 1 meter, or simply 5 meters. **
