WebFeb 7, 2007 · In the most general terms, the length of a perimeter (from the way you stated the question, I am assuming you are talking about a region of the plane, where the perimeter is a curve) is given as the integral of ds,where: ds 2 =dx 2 +dy 2. In practice, you would use: ds= (1+ (dy/dx) 2) 1/2 dx Feb 5, 2007 #3 HallsofIvy Science Advisor Homework Helper WebCalculating perimeter The perimeter is the distance all the way around the outside of a 2D shape.

How to Find Area and Perimeter: 11 Steps (with Pictures) - WikiHow
WebEach side measures 7cm and you can calculate the length of its outline in the following way. Perimeter = 7cm + 7cm + 7cm = 21cm. Or, there is an easier way. Since the three sides are the same, you can multiply one side by 3 and the result does not change. Perimeter = 3 x 7cm = 21cm. And this helps you with an equilateral triangle. WebPerimeter is the outside length/measurement of the shape. (For example, if a square's singulair side length is 2m, that you would add: 2+2+2+2= 8 to get the perimeter - since perimeter is the the path that surrounds the shape. I'm not sure if this makes it more confusing for you, but I hope it helps.) 1 comment ( 2 votes) Show more... KamdynK WebArea is the region occupied by a shape. Perimeter is total distance covered by the boundary of a shape. Area is measured in square units (m2, cm2, in2, etc.) Perimeter is measured in units (m, cm, in, feet, etc.) Example: Area of rectangular ground is equal to product of its length and breadth. cnf in import
