Algorithm of how to calculate the area of a square.

In order to calculate area of a square, 'A' be the area of square and the length of the square be 'a'. Then we need to calculate A= a*a. Step 2 :- Accept as input, the length of the sides of the square, and store the value in variable a. Step 3 :- Calculate the area of the square (a*a) and store in a variable A.

Explanation:

Area = side x side. For example, the area of a square of each side of length 8 feet is 8 times 8 or 64 square feet.
