Use: 2*pi*radius = circumference
To find the perimeters of a triangle you add the three sides together. if you get one of the two congruent sides you know the other congruent side. Then you use the pathagrium theorem to find the last side and add them up. Pathagrium theorem= a square + b square = c square where c is the hypotenuse
You use a ruler or similar object that is marked with centimeters. If your ruler only has inches, measure the inches, then multiply with 2.54 to get centimeters.

A tape measure, calibrated in inches.
You measure the linear inches with a ruler or tape measure, then you do the calculation to find out the area (length times width, if it is a rectangular shape).
Use: 2*pi*radius = circumference
It has MANY uses but it is primarily for creating a "no pass" zone to form perimeters through which no one is supposed to pass.
Use the "Tenths" scale of inches, or the centimetres and millimetres scale.
