The cost of fencing a rectangular garden of length 24 m and breadth 12 m at the rate of Rs 15 per metre is ___.

Given,

The length of the rectangular garden is 24 m

The breadth of the rectangular garden = 12 m

The perimeter of rectangle = 2 × (length + breadth) 

= 2 × (24 m + 12 m) 

= 2 × 36 m 

= 72 m

It is given that cost of fencing per 1 m of park = Rs 15

Therefore, the cost of fencing the rectangular garden = Rs 15 × 72 = Rs 1080
