Final answer:
The cost to fence Jane's garden, which has a perimeter of 19.8 meters, will be $44.55 given the fencing price of $2.25 per meter.
Step-by-step explanation:
The cost to put a fence around Jane's garden can be calculated by first determining the perimeter of the garden, and then multiplying that by the cost per meter of fencing. Jane's garden is a rectangle measuring 3.4 meters by 6.5 meters. To find the perimeter, add the lengths of all four sides:
Perimeter = 2 × (length + width) = 2 × (3.4 m + 6.5 m) = 2 × 9.9 m = 19.8 meters
Cost of fencing = perimeter × price per meter = 19.8 meters × $2.25/meter
Total cost = 19.8 m × $2.25/m = $44.55
Therefore, it will cost Jane $44.55 to put a fence around her garden.
