Square Formulas

A square is a convex quadrilateral having all sides of equal length and right angles to each other. It is also called a tetragon which is a regular polygon with four equal sides. The useful formulas to calculate the square area, perimeter, diagonal length, and side length are given below

  • Area of a Square Formula:
    • Area A = s²
  • The perimeter of a Square Formula:
    • Perimeter P = 4s
  • Diagonals of a Square Formula:
    • p = q = √(2s²) = s√2
  • Side of a Square Formula:
    • If square diagonal is given, then
      • Side length s = q / √2
    • If the square perimeter is given, then
      • Side length s = P / 4
    • If the square area is given, then
      • Side length s = √A

  • Process 3:
    • Note down the side length of the square.
    • Multiply the √2 with the side length to find the diagonal of a square.

Square Side Length:

  • Process 1:
    • Get the area of a square from the question.
    • Find the square root of the area to check the side length.
  • Process 2:
    • Note down the perimeter of the square.
    • Divide the perimeter by 4 to check the side length.
  • Process 3:
    • Check the diagonal length of a square.

Solved Example Questions on Square

Example 1: Square has a side of 52 m length. Find its area, diagonal length, and perimeter?

Solution:

Given that,

Side length of a square s = 52 m

Area of a square A = s²

= 52² = 52 * 52

= 2704

Square Perimeter P = 4s

= 4 * 52 = 208

Square diagonal length q = s√2

= √2 * 52

= 52√2 = 73.528

∴ Squre of 52 m side length has an area of 2704 m², perimeter of 208 m, diagonal length of 72.528 m.

Example 2: A square is having a diagonal length of 12 cm. What are the square side length, area, and perimeter?

Solution:

Given that,

Diagonal length of a square q = 12 cm

Side length of a square formula is s = q / √2

= 12 / √2

= 8.48

Area of a square formula is A = q² / 2

= 12² / 2

= (12 * 12) / 2

= 144 / 2

= 72

Perimeter of a square formula is P = 2√2 q

= 2√2 * 12

= 24√2 = 33.94

∴ Square of 12 cm diagonal has side length of 8.48 cm, area of 72 cm², perimeter of 72 cm.
