Question

In the figure drawn below, its dimensions are given in metres.

If $C=3$, find the total cost to fence the garden, if the cost of fencing is $Rs.7$ per metre.

• A. $Rs.356$
• B. $Rs360$
• C. $Rs322$
• D. $Rs375$

Answer 1

Answer: (C)

$Rs322$

In the given

The complete perimeter $=6+c+c+9+12+5+c+5$

$=37+3c$

At $c=3$

Perimeter $=37+3\times 3=46m$

Cost of fencing= Perimeter$\times$ Cost of fencing

$=46\times 7=Rs322$
