A square is a special rectangle in which all sides are equal. That is, all four angles of a square are right angles, 90 degrees.
Area of a square measures the interior space. It would give us an account of how much space the square covers.
The Formula
To find the area of a square, you use this formula:
Where:
a is the length of one side of the square.
Problem 1: Find the area of the square, whose side measures 16 cm.
Solution:
Side of the square is given, a = 16 cm
Area of the square
=
= 16
= 256
Problem 2: If the area of the square is given as 529 , then find length of its side.
Solution:
Area of the square = A = 529
Side of the square = a =?
Then, the length of side is 23 cm.
