Question

The perimeter of a square handkerchiet is
$\frac{4}{5} \: m$
Find the length of each side in metres​

Answer 1

Answer

1/5 m

Step-by-step explanation:

Perimeter of a square = 4a (a is the length of a side )

4/5=4a

so a=1/5 m

Answer 2

Answer:

1/5 m

Step-by-step explanation:

As per the provided information in the given question, we have :

• Perimeter of the square handkerchief = 4/5 m

We are asked to calculate the length of each side in metres.

In order to calculate the length of each side in metres, we'll be using the formula of perimeter of the square because we have the perimeter and unknown side, so we can find the length of each side using formula of perimeter of square which will act as a linear equation.

$\longmapsto\bf {Perimeter_{(Square)} = 4 \times Side }$

Substitute the value of perimeter of square given in the question.

$\longmapsto\rm {\dfrac{4}{5}\; m = 4 \times Side }$

Now, transpose 4 from R.H.S to L.H.S, its arithmetic operator will get changed.

$\longmapsto\rm {\dfrac{4}{5}\; m \div 4 = Side }$

By using the fraction rules, dividing the fraction by 4 in the L.H.S.

$\longmapsto\rm {\dfrac{4}{5}\; m \times\dfrac{1}{4} = Side }$

Multiplying the values in L.H.S.

$\longmapsto\rm {\dfrac{4}{20}\; m = Side }$

Reducing the fraction to the lowest terms in L.H.S.

$\longmapsto\bf {\dfrac{1}{5}\; m = Side }$

∴ Side of the square is 1/5 m.
