Question

find the cost of fencing a rectangular park of length 125m abd breadth 85 m at the ratw of ruppess 15 per metre​

Answer 1

Answer:

$perimeter \: of \: rectangle \: = \\ 2 \times (l \times b) \\ 2 \times (125 + 85) \\ = 2 \times210 \\ =420m$

$cost \: of \: fencing \\ \: per \: m \: = 15rs \\ then \: cost \: f \: fencing \: 420m \: \\ = 15 \times 420 \\ = 6300rs$

Answer 2

Given :-

• Length of rectangular park = 125 m
• Breadth of rectangular park = 85 m
• Rate of fencing = Rs. 15 per meter

To Find :-

• Cost of fencing = ?

Answer :-

It will cost Rs. 6300 to fence the park.

Explaination :-

→ Perimeter of reactangular park = 2(Length + Breadth)

→ Perimeter of reactangular park = 2(125 + 85)

→ Perimeter of reactangular park 2(210)

→ Perimeter of reactangular park = 420 m

→ Perimeter of reactangular park = Length of wire required

Now, let's find the cost of fencing :

➝ Cost of fencing 1 m wire = Rs. 15

➝ Cost of fencing 420 m wire = 15 × 420

➝ Cost of fencing 420 m wire = Rs. 6300

Therefore,it will cost Rs. 6300 to fence the park.
