First, let's convert the dimensions of the flower bed from yards to inches, since the cost of the edging is given per 12-inch stone.

1 yard = 36 inches.

So, a 6 yards by 1 yard flower bed would be 216 inches (6*36) by 36 inches.

Since you want a double layer of edging, you would need to calculate the perimeter of the flower bed and then double it.

The perimeter of a rectangle is given by the formula 2*(length + width).

So, the perimeter of the flower bed is 2*(216 + 36) = 504 inches.

Since you want a double layer, you would need 504 * 2 = 1008 inches of edging.

Each stone is 12 inches, so you would need 1008 / 12 = 84 stones.

The cost of the edging is N2.32 per stone, so the total cost would be 84 * N2.32 = N194.88.
