Question

The length and breadth of a rectangular plot are $900m$ and $700m$ respectively. If three rounds of fence is fixed around the field at the cost of $Rs$. $8$ per meter, the total amount spent is ?

• A. $Rs.768$
• B. $Rs.7680$
• C. $Rs.76800$
• D. $Rs.768000$

Answer 1

Answer: (C)

$Rs.76800$

$l=900,b=700$
Perimeter = $2(900+700)$
$=\left(1600\right)$
$=3200$
$3$ rounds of fence :
$=3\left(3200\right)$
$=9600m$
$9600\times 8$
$=Rs.76800$
