A rectangular garden has an area of 800 m. If it is 25 meters wide, find the cost of fencing it at $12 per meter.

Here, we need to find out what is the length of the rectangle. To do this, we'll divide 800 by 25: 800/25 = 32

So we now know that the length is 32 m and the width is 25 m. So we can now find the perimeter:

(32 + 32) + (25 + 25) =

64 + 50 = 114

The perimeter is 114 m. To find how much is will cost to fence 114 meters, we'll multiply the number of meters by the cost per meter: 114 * $12 = $1368

It will cost $1368.
