Square Formulas:

A square is a special case of the rectangle where the length is equal to the width. All 4 sides, designated s, are of equal length. If only the side, area or perimeter of a square is known, you can calculate the other 2 unknowns.

Area of a square:

a = s²

Perimeter of a Square

p = 4*s

Side of a Square

s = √a
s = p/4

Square Calculations

• Given the length of a side find the area and perimeter
  s is known; find a and p
  • a = s²
  • p = 4*s
• Given the area find the length of the sides and the perimeter
  a is known; find s and p
  • s = √a
  • p = 4*s
• Given the perimeter find the length of the sides and the area
  p is known; find s and a
  • s = p/4
  • a = s²
