Question

Find the cost of fencing a field in the shape of rectangle of length $25$ m, and breadth $15$ m, if the cost fencing is Rs $10$ a meter.

Answer 1

Length of Rectangle $25m$

Breadth of rectangle $15m$

The perimeter of rectangle $2(l+b)=2(15+25)2\left(4\right)=80m$

Cost for $1m$ is $10Rs.

Cost of $80m$ is $80\times 10=800Rs.$
