By using a metric tape measure. For example, if you want to measure off one acre, use your metric tape measure to measure off a square with all four sides 63.615 meters in length.
By using a metric tape measure
Square meters are a measure of area, not length. Therefore you could use square meters to measure the area of a basketball court.
Yes
a paper clip or a pencil
No. You can only measure a person's length using some sort of marked off stick or measuring tape. After you know the person's length, you can describe it in meters if you want to tell others about it.
Area = length x width If it is not one square divide the room up into small squares and add them together. Also Area of a triangle = (length x width)/2 The important thing is measure using meters. If you measure using ft then you will have to convert. If so, go to Google.com and type in something like 34 ft^2 in meters^2 it will give you the answer.
You can use any units of distance you want. If you measure the sides of a rectangle using feet, the area will be in square feet (ft²) If you measure using meters the area will be in square meters (m²) Here is an example of the math Area = length x width = 3 meters x 4 meters = 3x4 meters x meters = 12 square meters = 12 meters squared = 12 m²
The SI unit for volume is the cubic meter. But most common measurements are made using liters (cubic decimeters) or fractions of the liter (millliters / cubic centimeters).
Meters if you're using the metric system. Otherwise use feet.
Penguins, yourself, the depth of a swimming pool.
Americans need to start using metric units, this is so stupid, it's an acre-foot, who the hell knows what that would be.... just put it in meters cubed
