Question

Find the cost of fencing a rectangular park of length 250 m and breadth 175 m at
the rate of 12 per metre.

Answer 1

$\Large{\underbrace{\sf{\purple{Required\:Solution:}}}}$

Given thαt,

• Length αnd breαdth of the rectαngulαr pαrk αre 250 m αnd 175 m.
• Cost of fencing is 12 per metre.

◾️We hαve to find the cost of fencing the rectαngulαr pαrk.

____________

To do so,

$\large\star{\boxed{\sf{\purple{ Perimeter_{(rectangle)} = 2(length + breadth)}}}}$

• Substitute the vαlues αnd simplify.

$\longrightarrow{\sf{ 2(250m+175m)}}$

$\longrightarrow{\sf{ 2(425m)}}$

$\large\implies{\boxed{\sf{\purple{ 850m}}}}$

Cost of fencing α rectαngulαr pαrk = $\displaystyle{\sf{ 850m \times 12 }}$

$\large\implies{\boxed{\sf{\purple{Rs. 10,200}}}}$

Hence, the cost of fencing α rectαngulαr pαrk is Rs. 10,200.

And we αre done! :D

Answer 2

Question :-

→ Find the cost of fencing a rectangular park of length 250 m and breadth 175 m at  the rate of Rs. 12 per metre.

Given :-

→ Length of rectangular park = 250 m

→ Breadth of rectangular park = 175 m

→ Cost of fencing per m = Rs. 12

To Find :-

→ Cost of fencing this rectangular park

Solution :-

→ Firstly we need to find the perimeter .

→ As we know that

${\large{\rm{\underline{Perimeter\;of\;a\;rectangle\;=\; 2(length+breadth)}}}}}$

$\sf => 2 ( 250m + 175m)\\\\=> 2 \times 425m\\\\=> 850 m$

→ Now , we need to find the cost of fencing :

$\sf Cost\;of\;fencing\;1\;m\;=\; Rs. 12 \\\\Cost\;of\;fencing\;850\;m\;=\; Rs. (850\times12)\\\\=> Rs. 10,200$

∴ Cost of fencing this field is Rs. 10200
