Answer 2

Answer:

Perimeter of a square park is $48\ m$ .

Step-by-step explanation:

To find : perimeter of a square park .

Given :  area of park is 144m².​

Solution :

• As per given data we know that ,  area of square park is 144m².​
• We know that all four sides of square are equal .
• If ' $a$ ' is the side of square then area of square is given by,
• Area of square = $a^{2}$
• Therefore, by substituting the value in above formula we find side of square park .

        $144= a^{2} \\\\\sqrt{a^{2} } = \sqrt{144} \\\\a=12\ m$

• Perimeter of square park = $4a$

                                                  $=4\times 12\\\\= 48\ m$
