To answer this question I would need more details. Being that this is classified under plate tectonics I would need to know if you are talking about divergent, convergent or transform boundaries.
The plate boundary that caused Vesuvius to erupt is the convergence of the African and Eurasian plates. It stretches the length of the Italian Peninsula.
The Aleutian Trench is a tectonic plate boundary that is between the Aleutian Islands and Alaska. It is over 2000 miles in length.
Transform boundary
convergent boundary
At a convergent boundary. if seafloor is created at a divergent boundary then it must be the opposite (at a convergent boundary) where is being destroyed.
15200km
Perimeter
the perimeter
The boundary or perimeter of a circle is called the circumference. The formula for calculating the length of the circumference is C = 2πr.
15,200 km
It is the total length of the outer boundary of a plane shape.
The total length from the Northern Canada boundary to the Southern Canada boundary is 8890 kilometres.
The perimeter is the border or outer boundary around a two dimensional figure and is the length of such a boundary - a field for example, a perimeter fence
The plate boundary that caused Vesuvius to erupt is the convergence of the African and Eurasian plates. It stretches the length of the Italian Peninsula.
The perimeter of a plane figure is the length of its boundary. Thus the perimeter of a rectangle of length L and width W is 2L + 2W. The perimeter of a circle is the length of its circumference.
Not at all! The circumference is the length of the boundary of a circle. A chord is a straight line(or a line segment) that passes through two points on the boundary of a circle (or on a curve).
The perimeter. It is the total length of the boundary (where the fence is or will be) of the garden.
