A perimeter can be defined as the outside path or the outside boundary that surrounds a plane shape. It can also be defined as the length of the outline of a shape.
How To Find the Permiter of a Shape?
The simplest way to find a perimeter is by using a ruler to measure the length of the sides of a small regular or irregular shape. The perimeter is determined by adding the lengths of the sides/edges of the shape.
The perimeter of all shapes can be determined by adding the lengths of their sides/edges.
Perimeter of regular shape = 4cm + 4cm + 4cm + 4cm
Therefore, Perimeter = 16cm
Perimeter of irregular shape = 6cm + 8cm + 4cm + 5cm + 1cm + 4cm
Therefore, perimeter = 28cm
