Question

8 ) Find the perimeter of
square if its side is 5.2 cm
?​

Answer 1

$\large\sf\underline{Correct\:question\::}$

• Find the perimeter of square if its side is 5.2 cm.

‎

‎

$\large\sf\underline{Given\::}$

• Length of side of a square = 5.2 cm

‎

‎

$\large\sf\underline{To\:find\::}$

• Perimeter of the square whose side is 5.2 cm long.

‎

‎

$\large\sf\underline{Creating\:the\:road\:map\:for\:solution\::}$

We are provided with the measure of side of a square and we do know that all sides of a square are equal. So all sides of a square is 5.2 cm long. We are asked to find the perimeter of the square. Using the formula we can easily get the perimeter of the square. Let's proceed !

‎

‎

$\large\sf\underline{Solution\::}$

We know,

⍟ $\small\fbox\red{Perimeter\:of\:a\:square\:=\:4 × l}$

where :

• l stands for $\tt\orange{Length}$

‎

Now let's substitute the value in the formula :

$\sf\rightarrow\:Perimeter\:=\:4 \times 5.2$

$\sf\rightarrow\:Perimeter\:=\:4 \times \frac{52}{10}$

$\sf\rightarrow\:Perimeter\:=\:\frac{208}{10}$

$\small{\underline{\boxed{\mathrm\pink{\rightarrow\:Perimeter\:=\:20.8\:cm}}}}$★

$\large\sf\underline{Some\:other\:Formula\:related\:to\:square\::}$

• Area of a square = $\sf\:(side)^{2}$

• Diagonal of a square = $\sf\:\sqrt{2} \times side$

• Perimeter of the square = $\sf\:4 \times side$
