The outer boundary of a body or figure.
It means the distance around something. For polygons, just add the lengths of all the sides.
Twice (length + width)
the area is 18
56
81 mm
Add all of the sides of the shape together and you have the perimeter.
it is the area of a solid object times by the square root of the perimiter
It means the distance around something. For polygons, just add the lengths of all the sides.
circumference
base times height minus half of the perimiter base times height minus half of the perimiter
no...it's not
Twice (length + width)
56
the area is 18
perimiter
to find the perimiter you just add up all the sides....Perimiter is the same for every figure.
the perimiter =D
