What would you like to do?
We generally use the term perimeter to describe the distance around a geometric figure.
Is called the perimeter.
its perimeter or circumference, or boundary.
The distance around a closed plane figure is called the perimeter. The perimeter of a figure can be calculated by adding together the lengths of each side.
I hope this helps. When you are talking about figures such as squares, rectangles, and triangles, you call that its perimeter. If you want the mathematical formula to get per…imeter, you would use these: P= Perimeter, S= Side, b= base, h= height, l= length, w= width Square- P= 4s Rectangle- P=2b+2h OR P=2l+2wTriangle- P= a+b+c The distance around a circle, you would use circumference. It is really perimeter, but they call it circumference. This is its formula: C= Circumference, pi= 3.14159 etc, R= Radius, D= DiameterCircle- C= 2piR OR C= piD
The distance around a figure is called the "perimeter", unless the figure is a circle - in that case, it is called the "circumference".
