1. The expression to represent the area of the square will be a².

### What is the square?

The polygon of four sides of equal length and the adjacent line makes a right angle with each other.
The opposite sides of the square are parallel and equal.
The perimeter is the sum of all the sides of the square.
John measures the length of each side of a square.
He uses that value to calculate the perimeter of the square.
Let a square with a side length of a unit.
Then the perimeter is given as,
Perimeter of the square = 4a unit
P = 4a
The area of the square is given as,
Area = (Side)²
A = a²
Then the expression to represent the area of the square will be a².
