The perimeter of a square with 5 cm side is __

Concept:

Square:

• In Geometry, a square is a two-dimensional plane figure with four equal sides and all four angles are equal to 90 degrees.
• Sum of the four angles of the square is 360°.
• The properties of the rectangle are somewhat similar to a square, but the difference between the two is, a rectangle has only its opposite sides equal.
• Therefore, a rectangle is called a square only if all its four sides are of equal length.
• Square is a regular quadrilateral, which has all four sides of equal length and all four angles are also equal.
• Also, the diagonals of the square are equal and bisect each other at 90 degrees.
• A square can also be defined as a rectangle where two opposite sides have equal lengths.

Perimeter of a square = 4 × side

Calculation:

Given:

side = 5 cm

∴ Perimeter of the square = 4 × side = 4 × 5 = 20 cm
