You use linear units to express it, such as meters or millimeters, if that's what you mean.
Perimeter is in feet and not in square feet
linear, if side is x then perimeter is 4x
Because the perimeter is a linear measurement, and area is measured by multiplying 2 linear measurements together.
Perimeter is measured in Linear Units because it is Measurement of The Outline or Path of a given shape or area; a Perimeter is NOT the Measurement of What is Inside that Outline/Path. It is a One-Dimensional measurement, which MEANS it is a Linear Unit Measurement, such as Feet or Meters.Alternatively, a Two-Dimensional Measurement, is the Square of a Linear Unit -- like AREA is a Two-Dimensional Measurement and therefore Measured in Linear Units Squared (i.e. meters2/Square Meters or feet2/Square Feet). Area is the Measurement of What is Contained within a given Perimeter.
Neither. Volume is cubic units and area is square units. Perimeter is just units.
A square can't have a circumference. That's only for circles squares have area, volume, or perimeter.
y=4x
There's no way to calculate that just from square footage.
It is a strict linear relationship. Double the size, double the perimeter. The area, however, increases by the square of the scale factor.
Because a perimeter is measured in linear units while an area is measured in square units.
you don't. that's like asking how many dollars are in 10 feet. the units "linear feet" and "square feet" represent two totally different types of quantities. if you have a rectangle made up of 216 linear feet, the area (in square feet) could be practically anything. If the sides are 50 and 58, the perimeter is 216 linear feet and the area is 2,900 square feet. But if the sides are 10 and 98 feet, the perimeter is still 216 linear feet, while the area is now 980 square feet.
Linear units are used for perimeter because perimeter measures the total length around a shape, which is a one-dimensional measurement. In contrast, area measures the extent of a surface in two dimensions, requiring the multiplication of two linear measurements (length and width), resulting in square units. This distinction helps accurately represent the different dimensions involved in each measurement.
