Answer 1

The length of the wire is 60m ant the cost is Rs 300

Answer 2

Answer :-

The Perimeter of Rectangle is 60 m

The Cost of Fencing the Rectangle is Rs.300

Explanation :-

Given :

Length of the Rectangle = 20 m

Breadth of the Rectangle = 10 m

Rate of Fencing = Rs.5 per m.

To find :

The Length of wire to Fence and cost of Fencing

Solution :-

$\star$ Perimeter of Rectangle :

$\boxed{\underline{\sf \:2( length + breadth)}}$

$\sf{\implies}2(20 + 10)$

$\sf{\implies}40 + 20$

$\sf{\implies}60$

$\therefore$The Perimeter of Rectangle is 60 m

$\star$ Cost of Fencing :

$\sf{\implies}60 \times 5$

$\sf{\implies}300$

$\therefore$The Cost of Fencing the Rectangle is Rs.300
