Question

A rectangular garden is $32m$ wide and $48m$ long. How much fencing will be needed to enclose the garden? If fencing costs $Rs.98$ per metre, how much will it cost to fence the garden?

• A. $160m,Rs.15680$
• B. $180m,Rs.15680$
• C. $160m,Rs.15000$
• D. $170m,Rs.15600$

Answer 1

The correct option is A $160m,Rs.15680$

Length of garden $=48m$
Breadth of garden $=32m$
Perimeter $=2(48+32)m=160m$
$\therefore$ Length of fencing used to enclose the garden $=160m$
Cost of fencing $1m=Rs.98$
$\therefore$ Cost of fencing $160m=Rs.(98\times 160)=Rs.15680$
So, total cost $=Rs.15680$.
