☆ Solution ☆

Given :-

• The cost of fencing a rectangular Park 300 long and 200 wide at the rate of Rs 4 per metre.

To Find :-

• The cost of fencing a rectangular Park.

Step-by-Step-Explaination :-

As we know that :-

Perimeter of rectangle = 2 ( l + b )

Putting the respective value,

Perimeter of rectangle = 2 ( 300 + 200 )

Perimeter of rectangle = 2 × 500

Perimeter of rectangle = 1000

Hence,
