22​

Answer 1

Answer:

18 cm

Step-by-step explanation:

Area of square= SidexSide

324= A^2

So A= root of 324

= 18

Answer 2

Given :

• Area of a square handkerchief is 324 cm²

To calculate :

• The measure of side of a square.

Calculation :

Here, it's given that area of square handkerchief is 324 cm². And we are asked to find the measure of side of square.

As we know that,

• $\underline{ \boxed{ \rm{Area_{(Square)} = (side)^2}}}$

Now, calculating the measure of side of square by squaring the area of square handkerchief,

$: \implies \rm Side_{(Square \: handkerchief)} = \sqrt{324 \: cm^2}$

On removing the square roots,

$: \implies \underline{\boxed{\rm Side_{(Square \: handkerchief)} = {18 \: cm}}}\pink{ \bigstar}$

Therefore, the measure of side of a square handkerchief is 18 cm.

Verification:

Let's check our answer!

As we know that, formula for area of square is given by :-

• $\underline{ \boxed{ \rm{Area_{(Square)} = (side)^2}}}$

Here,

• The measure of side of square = 18 cm

Plugging the values in the equation:

$: \implies \rm Area_{(Square)} = 18 \: cm \times 18 \: cm$

Multiplying the numbers,

$: \implies \underline{\boxed{\rm Area_{(Square)} = {324 \: cm^2}}}\blue{ \bigstar}$

Hence, verified!
