What is area of square?
The number of square units required to fill a square is known as its area. In general, the area is defined as the space inside a flat object. The measurement is done in square units, with square meters being the usual unit (m2).
There are pre-defined formulas for calculating area for squares, rectangles, circles, triangles, and other shapes. The area of a square will be discussed in this article.
How to calculate?
In figure radius of circle which is side of square too Hence r=a
Circumference =[tex]2\pi r=9.42\\[/tex]
using[tex]\pi =3.14[/tex]
=[tex]2r=9.42/3.14[/tex]
r=3/2
r=1.5
now r=s=1.5
Hence area of square = [tex]s^{2} =1.5^{2}[/tex]=2.25
