2=288

3=62.0

Step-by-step explanation:

1=P of square=4*side

=30*4=120

2=72*4=288

3=15.5*4=62.0

Answer 2

${\underline{\underline{\large{\textsf{\textbf{\pink{Given :}}}}}}}$

• 30 cm
• 72 m
• 15.5 cm

${\underline{\underline{\large{\textsf{\textbf{\pink{To Find :}}}}}}}$

The perimeter of the square.

${\underline{\underline{\large{\textsf{\textbf{\pink{Formula Used :}}}}}}}$

${\underline{ \boxed{\frak{\blue{perimeter \: of \: square = 4 \times (side)}}}}}$

${\underline{\underline{\large{\textsf{\textbf{\pink{Solution :}}}}}}}$

• 30 cm

We know that,

Perimeter of square = $\sf{4 × (side)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = $\sf{4 × (30)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ = ${\frak{\blue{120 cm}}}$

Therefore,

${\sf{Perimeter \ of \ square \ is}{\textsf{\textbf{\red{ \ 120cm}}}}}$

• 72 cm

We know that,

Perimeter of square = $\sf{4 × (side)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= $\sf{4 × (72)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= ${\frak{\blue{288 cm}}}$

Therefore,

${\sf{Perimeter \ of \ square \ is}{\textsf{\textbf{\red{ \ 288cm}}}}}$

• 15.5

Perimeter of square = $\sf{4 × (side)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= $\sf{4 × (15.5)}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= ${\frak{\blue{ 62cm}}}$

Therefore,

${\sf{Perimeter \ of \ square \ is}{\textsf{\textbf{\red{ \ 62cm}}}}}$

${\underline{\underline{\large{\textsf{\textbf{\pink{Additional Information :}}}}}}}$
