Question

the perimeter of a square field is 20 cm then the area is

Answer 1

4*side = Perimeter of square field.
4*s = 20
s = 5

Therefore, Area = side * side
= 5*5 = 25 square cm

Answer 2

$\textsf{\large{Answer :-}}$

$\textsf{The area is 25sq.cm}$

$\textsf{\large{Explaination:- }}$

$\textsf{\large{Given;- }}$

$\textsf{Perimeter of the square= 20 cm.}$

$\textsf{\large{To find :-}}$

$\textsf{The area}$

$\textsf{\large{Solution :-}}$

First we need to find the side of the square.

$\textbf{\underline{Perimeter \: of \: square = \: }}$

$\tt{ \Rightarrow \: Side\times 4 }$

$\tt{ \Rightarrow \: side \times 4 = 20}$

$\tt{ \Rightarrow \: side = 20 \div 4 }$

$\tt{ \Rightarrow \: side = \dfrac{20}{4} }$

$\tt{ \Rightarrow \: side \: = 5cm}$

$\textbf{\underline{Area of Square}}$

$\tt{ \Rightarrow \: (side)^{2} }$

$\tt{ \Rightarrow \: (5)^{2} }$

$\tt{ \Rightarrow \: 25 \: sq.cm}$

$\therefore$The area of the Square is 25 sq.cm
