How much is perimeter?

The perimeter is the measure of length of the boundary of a 2-dimensional object. The most common mathematical objects in this category are squares, rectangles, circles and triangles. The perimeter of a square = 4d (where d is the length of 1 side) The perimeter of a rectangle = 2l + 2w (where l is the length and w is the width) The perimeter of a circle = 2πr (where π is the mathematical constant pi and r is the radius. The perimeter of a circle is better known as the circumference) The perimeter of a triangle is the total length of all three sides.
