Question

How do u find the perimeter of somthing

Answer 1

Lets say that the length of a rectangle is 12 cm and the width is 5 cm, you would add 12+12+5+5 (as in the length on both length sides and the width on both sides) so the perimeter of this rectangle is: 34 cm

Answer 2

We add all the sides to get the perimeter.
I've added an image to give you a visual understanding as well.
