The length of a rectangular park is 620 m and its breadth is 0.5 km. Find the cost of fencing the park at the rate of Rs. 8 per metre.
Given:
Length of the park $= 620\ m$.
Breadth of the park $= 0.5\ km$.
Cost of fencing the park$=Rs.\ 8$ per metre.
To do:
Here, we have to find the total cost of fencing the park.
Solution:
We know that,
$1\ km=1000\ m$
Perimeter of rectangle $=2$(Length $+$ Breadth)
Therefore,
Length of the park $= 620\ m$.
Breadth of the park $= 0.5\times1000\ m=500\ m$
Perimeter of the rectangular park $=2(620+500)\ m$
$=2(1120)\ m$
$=2240\ m$
Cost of fencing $1\ m= Rs.\ 8$.
Cost of fencing the park of $2240\ m = Rs.\ 8 \times 2240=Rs.\ 17920$
The total cost of fencing the park is Rs. 17920.
