If the cost of fencing a rectangular park at the rate of 7.50 per metre is 600 and the length of the park is 24m, find the breadth of the park
Given:
The cost of fencing a rectangular park at the rate of 7.50 per metre is 600 and the length of the park is 24m
To do:
We have to find the breadth of the park.
Solution:
We know that,
Perimeter of rectangle $=2$(Length $+$ Breadth)
Therefore,
Length of the park $= 24\ m$.
Let the breadth of the park be $x$.
This implies,
Perimeter of the rectangular park $=2(24+x)\ m$
Cost of fencing $1\ m= Rs.\ 7.50$.
Cost of fencing the park of $2(24+x)\ m = Rs.\ 7.50 \times 2(24+x)$
Therefore,
$15(24+x)=600$
$24+x=40$
$x=40-24$
$x=16\ m$
The breadth of the park is $16\ m$.
