Understanding the Perimeter of Geometric Shapes and Calculating it Easily

Perimeter

The perimeter of a shape is the distance around the outside of the shape

The perimeter of a shape is the distance around the outside of the shape. It is the total length of all the sides of the shape.

The formula for finding the perimeter of common geometric shapes is as follows:

– Square: Perimeter = 4 × side length
– Rectangle: Perimeter = 2 × (length + width)
– Triangle: Perimeter = sum of the lengths of all three sides
– Circle: Perimeter = 2 × π × radius

For example, let’s say we have a square with a side length of 5 units. To find the perimeter, we simply multiply the side length by 4:

Perimeter = 4 × 5 = 20 units.

So, in this case, the perimeter of the square is 20 units, meaning it would take 20 units of length to walk around the square if each side is 5 units long.

It’s important to note that the perimeter is always expressed in the same unit as the length of the sides. For example, if the side length of a square is given in inches, the perimeter will be in inches as well.
