the rate of 13 per metre.​

Answer 1

☆ Solution ☆

Given :-

• The cost of fencing a rectangular park of length 225 m and breadth 115 m at the rate of 13 per metre.

To Find :-

• The cost

Step-by-Step-Explaination

We know circumference and perimeter is same.

So,

Perimeter of rectangle = 2 ( l + b )

In which,

l and b are length and breadth of rectangle respectively.

l = 225 m

b = 115 m

Put the values in formula :

=> 2 ( 225 + 115 )

=> 2 × 340

=> 680

Perimeter = Circumference

Circumference of rectangular park is 680 m.

If, Cost of fencing 1 m = Rs. 13

Then, Cost of fencing 680 m :

=> 680 × 13

=> 8840

Therefore,

Cost of fencing rectangular park is Rs.8840

Answer 2

Answer:

length =225m

breadth =115m

area of the rectangular park =225×115

=25,875 sq/m

again,

cost of the fencing 1sq/m the park=rs 13

" " " 25,875sq /m "=rs13 ÷1 sq/m ×25,875

= rs 336,378

hence, the cost of fencing the park is rs 336,378
