Square perimeter

The formula for the perimeter of a square

O = a + a +a +a = 4 • a

Legend:

O – the perimeter of the square

a – the length of the side of the square

 

Sample task:

Calculate the perimeter of the square with the side length a = 6 cm.

O = 6 + 6 +6 +6 cm

O = 24 cm

or

O = 4 · 6 cm

O = 24 cm
