Answer 1

Explanation:

Question 1

• Side of Square = 3.8 cm

We can find Perimeter of square using perimeter formula that is ${\sf{ Perimeter_{(Square)} = 4a }}$

$\colon\implies{\sf{ 4 \times 3.8 }} \\ \\ \colon\implies{\sf{ 15.2 \ cm }}$

Question 2

• Side of Square = 4.6 m

${\sf{ Perimeter_{(Square)} = 4a }}$

$\colon\implies{\sf{ 4 \times 4.6 }} \\ \\ \colon\implies{\sf{ 18.4 \ m }}$

Question 3

• Side of Square = 2m 5dm = 2.5 m

We also Know that:-

${\sf{ Perimeter_{(Square)} = 4a }}$

$\colon\implies{\sf{ 4 \times 2.5 }} \\ \\ \colon\implies{\sf{ 10 \ m }}$

Hence,

Your all Required answers are mentioned above!

Answer 2

Answer:

1) perimeter of square = 4 × side

given by question,

perimeter of square = (4 × 3.8)cm

perimeter of square = 15.2cm

2) perimeter of square = 4 × side

given by question,

perimeter of square = (4× 4.6)m

perimeter of square = 18.4m

3) perimeter of square = 4 × side

given by question,

perimeter of square = 4× 2.5m

perimeter of square = 10m
