b) 20 cm
c) 16 cm
d) 25 sq. cm​

Answer 1

Answer :-

• Option c is correct.
• The perimeter of the square is 16 cm.

To find :-

• The perimeter of a square whose side is 4 cm.

Step-by-step explanation :-

• Here, the length of the side of a square has been given to us. We have to find it's perimeter.

We know that :-

$\underline{\boxed{\sf Perimeter \: of \:a \:square = 4 \times Side}}$

Here,

• Side = 4 cm.

------------------------------

Hence,

$\bf Perimeter = 4 \times 4$

Multiplying 4 with 4,

$\overline{\boxed{\bf Perimeter = 16 \: cm}}$

• So, the perimeter of the square is 16 cm.

• Hence, option c is correct.
