Question

the perimeter of a square is 20cm, area of square is​

Answer 1

Given :-

• The perimeter of a square is 20cm

To Find :-

• What is the area of square

Formulas Used :-

$\bigstar \: \boxed{ \bf \color{magenta}Perimeter _{(Square)} \: = \: 4 \times Side} \: \bigstar$

$\bigstar \: \boxed{ \bf \color{magenta} Area_{(Square)} \: = \: Side\times Side} \: \bigstar$

Solution :-

First, We have to find the side of a square :

Given :

• Perimeter = 20cm

According to the question by using formula we get,

$: \implies \: \bf Perimeter _{(Square)} \: = \: 4 \times Side$

$: \implies \: \sf 20cm \: = \: 4 \times Side$

$\displaystyle: \implies \: \sf \cancel\frac{20}{4} \: = \:Side$

$\displaystyle: \implies \: \sf \frac{5}{1} \: = \:Side$

$\displaystyle: \implies \: \sf 5 \: = \:Side$

$\displaystyle: \implies \: \bf \red{ Side \: = \: 5}$

Hence, The side of a square is 5 cm .

Now, We have to find the area of a square :

Given :

• Side = 5 cm

According to the question by using formula we get,

$⇢ \: \: \bf Area_{(Square)} \: = \: Side\times Side$

$⇢ \: \: \sf Area_{(Square)} \: = \: 5 \: cm\times 5 \: m$

$⇢ \: \: \bf \red{Area_{(Square)} \: = \: 25 \: {cm}^{2} }$

∴ The area of a square is 25 cm² .
