Asquare is a quadrilateral with four equal sides and four equal angles. determine an expression for the perimeter of a square, given that each side has a length of units. 2 + + + (4) ∙

P = 4*a  or P = a + a + a + a

Step-by-step explanation:

Given that each side has a length of units, assume the length is a.

The perimeter of a square (quadrilateral) is given by:

P = 4*a  or P = a + a + a + a

Example 1: Find the area and perimeter of the square whose side length is 2 meters.

Solution:

Given that:

a = 4m

Perimeter of the square = 4 × 2 = 8 m
