Answer
The perimeter is the length of the outside.

For a triangle, it is the sum of the length of the three sides.
If the sides were of length a, b, and c, the perimeter would be
a+b+c.

For a square, it is 4n where n is the lengthof a side.

For a circle, it is 2*pi*r, where pi is 3.14159... and r is the radius.
