Question

3. Ravi wants to fence his square field with side 22 m 80 cm, 5 times. How much wire does he need? (2)​

Answer 1

Given :

• Side of the Square = 22 m 80 cm
• No. of time fenced = 5

To Find :

• Wire required for fencing = ?

SolutioN :

~ Formula Used :

• ${\underline{\boxed{\pmb{\sf{ Perimeter = 4 \times Side }}}}}$

$\\ \qquad{\rule{150pt}{1pt}}$

~ Calculating the Perimeter :

${\longmapsto{\qquad{\sf{ Perimeter = 4 \times Side }}}} \\ \\ \\ \ {\longmapsto{\qquad{\sf{ Perimeter = 4 \times 22.80 }}}} \\ \\ \\ \ {\qquad \; \; {\therefore \; {\underline{\boxed{\red{\pmb{\frak{ Perimeter = 91.2 \; m}}}}}}}}$

$\\ \qquad{\rule{150pt}{1pt}}$

~ Calculating the Cost :

${\dashrightarrow{\qquad{\sf{ Cost = Perimeter \times No. \; of \; Rounds }}}} \\ \\ \\ \ {\dashrightarrow{\qquad{\sf{ Cost = 91.2 \times 5 }}}} \\ \\ \\ \ {\qquad \; \; {\therefore \; {\underline{\boxed{\purple{\pmb{\frak{ Wire \; Required = 456 \; m}}}}}}}}$

$\\ \qquad{\rule{150pt}{1pt}}$

~ Therefore :

Wire required to fence the field is 456 m .
