Answer 2

Answer:

Area of square is $3600 \ cm ^{2}$ .

Step-by-step explanation:

To find : area of square

Given : perimeter of square is 240cm​ .

Solution :

• We know that all four sides of square are equal .
• If ' $a$ ' is the side of square then perimeter of square is given by,

        Perimeter of square $=4 a$

• Therefore, by substituting the value in above formula we find side of square.

          $240 = 4a \\\\ a = \frac{240}{4} \\\\ a = 60\ cm$

• Area of square = $a^{2}$

                                  $= ( 60 )^{2} \\= 3600\ cm ^{2}$
