Answer 2

To find : cost of fencing field at rate of $Rs \ 15$ .

Given : length = $12\ m$ and breadth = $8\ m$

Solution :

• According to question we are given that length and breadth of  rectangular field is $12\ m$  and $8\ m$ respectively. We have to find cost of fencing field.

• To find perimeter we use following formula -

        Perimeter of field = $2 ( l + b)$

• Substituting the values we get,

      Perimeter of field = $2 ( 12 + 8 ) \ m$

                                    $= 2\times 20\ m\\= 40 \ m$

• Cost of fencing  = $40 \times 15$

                                   $= 600 \ Rs$

Hence, Cost of fencing  rectangular field at rate of $Rs \ 15$ is $Rs \ 600$ .
