Step-by-step explanation:

Answer 2

To find : length  of square

Given : Area of square = $169\ cm ^{2}$

Solution :

• 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 length of side of square.

• Area of square $= a ^{2}$  

                              $169 = a^{2} \\a = 13$

Hence, length of side  of square is $13\ cm$ .
