Kate wants to build a fence around her garden to prevent rabbits from eating her vegetables. The rabbit fencing costs $7.50 per metre. How much will it cost to enclose a square garden with an area of 144 m2?
and then multiply that by 4, since the square has 4 sides.
square root of 144 = 12 meters on a side
12 * 7.5 = $ ?_____________

To find the cost of enclosing a square garden with an area of 144 m^2, you need to calculate the perimeter of the garden and then multiply it by the cost per meter of the rabbit fencing.
First, you need to find the length of one side of the square garden. Since the garden is a square, all sides are equal. To do this, you can take the square root of the area:
Side length = √(Area)
Side length = √(144 m^2)
Side length = 12 m
Next, calculate the perimeter of the garden. Since all sides are equal, you can multiply the side length by 4:
Perimeter = Side length * 4
Perimeter = 12 m * 4
Perimeter = 48 m
Finally, multiply the perimeter by the cost per meter of the rabbit fencing:
Cost = Perimeter * Cost per meter
Cost = 48 m * $7.50/m
Cost = $360
Therefore, it will cost $360 to enclose a square garden with an area of 144 m^2.
