Question

The length of a rectangular playground is $40m$ and breadth is $15m$. Find the cost of fencing it at the rate of ₹ $5$ per metre.

• A. $₹550$
• B. $₹650$
• C. $₹1050$
• D. $₹750$

Answer 1

The correct option is A $₹550$

Given:
The playground is rectangular in shape with length = 40m and breadth = 15m.

Perimeter of a rectangle = $2\times$ (length + breadth )
$\Rightarrow P=2\times (40m+15m)=110m$

Cost of fencing 1 metre of the playground = $₹5$

Cost of fencing the playground = (Cost of fencing 1 m of the playground) $\times$ (Perimeter of the rectangle)

$\Rightarrow$Cost of fencing = $₹5\times 110m=₹550$
Therefore, cost of fencing the playground will be $₹550$.
