Question

A rectangular park is 90m long and 70m wide. Find the length of the wire required to fence around it. ​

Answer 1

Answer:

The length of the wire would be 320m.

Step-by-step explanation:

To find out the length of the fence we first need to find out the perimeter of rectangle:

Perimeter of rectangle = 2(l+b)

= 2(90+70)

= 2 x 160

= 320 m

Answer 2

Given

• Length of the rectangle = 90m
• Breadth of the rectangle = 70m

⠀

To find

• Length of the wire required to fence around it.

⠀

Solution

• Whenever question is related to fencing, we have to find the perimeter.

⠀

We know that

$\: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt{\bigstar{Perimeter_{(Rectangle)} = 2(l + b){\bigstar}}}}$

⠀

$\large{\tt{\longmapsto{Perimeter = 2(90 + 70)}}}$

⠀

$\large{\tt{\longmapsto{Perimeter = 2 \times 160}}}$

⠀

$\large{\tt{\longmapsto{Perimeter = 320m}}}$

⠀

→ Since, wire will be surrounded around the park.

Therefore, Perimeter of the park is equal to the Length of the wire required to fence around it.

Hence,

• Length of the wire = 320m
