If you swam 210 lengths and each length is 25 meters..how many meters did you swim?
210 times 25 meters=5,250 meters (or 5.25 kilometers)
meters are a measure of length meters squared are a measure of area They measure different things and cannot be directly converted. However, if you are given the lengths of, say, a rectangle, multiplying the two lengths (each measured in meters) together will find the area (measured in meters squared).
Which metric unit of length would you use to measure the length of a piece of wire with the greatest accuracy?
The SI unit of length is the meter. Shorter lengths are commonly expressed in centimeters, or millimeters. The chosen unit doesn't affect accuracy; if the wire has (for example) a length of 245 millimeters, then each of these measurements: 245 millimeters, 24.5 centimeters, 2.45 decimeters or 0.245 meters are just as accurate as the others. The SI unit of length is the meter. Shorter lengths are commonly expressed in centimeters, or millimeters. The chosen unit…
