Question

The area of given unit is 1 sq cm then find out the area and perimeter of square

Answer 1

Answer:

Step-by-step explanation:

The formula of perimeter and area of square are explained step-by-step with solved examples.

If 'a' denotes the side of the square, then, length of each side of a square is 'a' units

perimeter and area of square

Perimeter of square = AB + BC + CD + DA  

                             = (a + a + a + a) units  

                             = 4a units  

● Perimeter of the square = 4a units  

We know that the area of the square is given by  

Area = side × side  

A = a × a sq. units

Therefore, A = a² square units  

Therefore, a² = A Here, a is the side of the square.  

Therefore, a² = √A

Therefore, side of the square = √Area
