Question

What is the perimeter?what are its units​

Answer 1

Answer:

The perimeter of a shape is the total distance around the shape, or the lengths of its sides added together. Perimeter (P) is measured in units such as millimetres (mm), centimetres (cm) and metres (m).

Answer 2

The perimeter of a two-dimensional shape is the distance around the shape. It is found by adding up all the sides (as long as they are all the same unit). The area of a two-dimensional shape is found by counting the number of squares that cover the shape.

The perimeter is the measured length of such a boundary. In geometry, it is defined as the sum of the distance of all the lengths of the sides of an object. Perimeter is measured in any unit of length, e.g. metres, centimetres, miles or inches.
