Question

A rectangle field is 640 meter long and 365 meter wide what is the total length of the fence around the field in kilometers

Answer 1

GIVEN:

• Length of the rectangular field = 640 m
• Breadth of the rectangular field = 365 m

TO FIND:

• What is the perimeter of the rectangular field ?

SOLUTION:

We have given that, the length and breadth of the rectangular field are 640 m and 365 m respectively.

We know that the formula for finding the perimeter of rectangle is:-

$\large{\boxed{\bf{\star \: PERIMETER = 2(L+B) \: \star}}}$

According to question:-

• Length = 640 m
• Breadth = 365 m

$\rm{\hookrightarrow Perimeter = 2(640+365) }$

$\rm{\hookrightarrow Perimeter = 2 \times 1005 }$

$\rm{\hookrightarrow Perimeter = 2010 \: m }$

Convert the perimeter into km:-

• 1 m = $\bf{\dfrac{1}{1000} \: km}$
• 2010 m = $\bf{\dfrac{2010}{1000} km}$
• 2010 m = 2.01 km

❝ Hence, the total length of the fence around the field is 2.01 km ❞
