Because length is one dimension, thus it's measured in linear units.
Because the perimeter is a linear measurement, and area is measured by multiplying 2 linear measurements together.
No. Just like a length, a perimeter is measured in linear units.
Arc length is measured in linear units because it represents a distance along the curved path of a circle or any curve. Just like the length of a straight line is expressed in units such as meters or feet, the arc length quantifies the distance traveled along the curve in the same way. This consistency allows for direct comparisons and calculations involving different types of lengths, whether they are linear or curved.
You can mutiply or divide the units to find the answer.
perimeter
Because a perimeter is measured in linear units while an area is measured in square units.
Because the perimeter is a linear measurement, and area is measured by multiplying 2 linear measurements together.
No. Just like a length, a perimeter is measured in linear units.
Focal length is measured in milimeters (mm) -----------------------------------------------------------------
You can mutiply or divide the units to find the answer.
perimeter
Yes. But, it is seldom used.
All lengths are measured in metres.
no it will not change if the lengths are different units. That is because it is defined as length/length per degree and as you see length cancels out. Its units are simply per degree only
Neither. Volume is cubic units and area is square units. Perimeter is just units.
No - because time is measured in seconds, not linear distance.
Angular displacements measured in radians or stradians, lengths of lines measured in units of length.
