Question

find the length of wire required to go three times around the boundary of a rectangular field that is 36,000m long and 44,000m wide 6th class holiday homework

Answer 1

$\mathfrak{\large{\underline{\underline{Answer :-}}}}$

The Length of the Wire is 480000 m or 480 km.

$\mathfrak{\large{\underline{\underline{Explanation :-}}}}$

Given :

Length of the field = 36,000 m

Breadth of the field = 44,000 m

Wire which needs to go = 3 times around the boundary.

To find :

The Length of the Wire

Solution :

First find the Perimeter of the Rectangular field.

★ $\boxed{\sf{Perimeter = 2(Length + Breadth)}}$

$\sf{\implies} \: 2(36000 + 44000)$

$\sf{\implies} \: 72000 + 88000$

$\sf{\implies} \: 160000$

Perimeter of the Rectangle = 1,60,000 m

$\rule{300}{1.5}$

Multiply the Perimeter by 3 as the Wire needs to be taken 3 times around the Rectangle.

$\sf{\implies} \: 160000 \times 3$

$\sf{\implies} \: 480000$

The Wire should be 480000 m long.

$\rule{300}{1.5}$

For the ease of understanding, We can convert the Length of the Wire into km.

★ $\boxed{\sf{1 km = 1000 m}}$

$\sf{\implies} \: \dfrac{480\cancel{000}}{1\cancel{000}}$

$\sf{\implies} \:480$

$\therefore$ The Length of the Wire is 480000 m or 480 km.

Answer 2

Answer:

480000 m

Step-by-step explanation:

1 round =perimeter

perimeter = 2 (length + breadth)

2 × 80000

= 160000 meter

for 3 rounds.....160000 x 3

=480000 metres
