Earth is a sphere so it doesn't have a perimeter. Circles have perimeters. However, if you wanted to know it's surface area then that is 510,072,000 km².
56
Twice (length + width)
the area is 18
The perimeter of a circle is its circumference
The outer boundary of a body or figure.
it is the area of a solid object times by the square root of the perimiter
circumference
no...it's not
base times height minus half of the perimiter base times height minus half of the perimiter
it measures by perimiter it measures by perimiter
perimiter
56
Twice (length + width)
the area is 18
the perimiter =D
multiply all of the sides than that is your answer
No, squares do not represent perimeters.
