Question

Find the cost of fencing a rectangle park of length 175m and breadth 125m at the rate of Rs.12 per meter.

Answer 1

Hint: Here the given question is to find the value for the fencing of the rectangular park, where we are provided with length and the breadth of the rectangle. After finding the perimeter we are given the cost of per meter of fencing and then calculate the total cost of fencing.
Formulae Used: Perimeter of the rectangle is:
\[ \Rightarrow perimeter = 2(l + b)\]

Complete step-by-step solution:
Here we need to find the total cost of fencing and for that we need to find the perimeter of the park and then for the total cost, on solving we get:
\[ \Rightarrow perimeter = 2(l + b)\]
Now putting the value we get:
\[ \Rightarrow perimeter = 2(175 + 125) = 2(300) = 600m\]
On finding the cost of fencing, here we need to find the total cost we need to multiply with the fencing cost we get:
\[ \Rightarrow 600 \times 12 = Rs7200\]
It is the total cost for the fencing.

Note: In the given question here we need to solve for the cost of fencing, and to find the total cost, we are provided with the cost of fencing for per meter, and once the total parameter is obtained then we need to multiply by the per meter cost and total price will be obtained.
