You add all the sides
The perimeter would be 16 meters.
Metre.
I would use kilometers.
You could but it would not be a particularly meaningful measure.
to measure the perimeter we need a figure with boundaries and all the sides with dimensions
A measuring wheel you just walk it and it does all the counting
The measure of a perimeter is the total length of all sides of a geometric shape, so any shape with a combination of sides whose total is 27 would yield this perimeter.
I would use a ruler or a tape measure. After I was done, I would express the measurement in centimeters or inches.
in math terms, the perimeter is the measure around the shape.
Perimeter is in feet and not in square feet
The measure of a perimeter can be any positive number.
i would use feet or inches depending on the size
