calculate, to 1 decimal place, the amount of fencing you would need to enclose a square garden that is 42m squared

if the area is 42 m^2, the side is √42 m

So, the perimeter is 4√42 m.
Now just do the math...

To calculate the amount of fencing needed to enclose a square garden, you would first find the perimeter of the square. The perimeter is the sum of all four sides.

Since the garden is square, all sides are equal in length. To find the length of each side, take the square root of the area of the garden.

In this case, the area of the garden is given as 42 square meters. Taking the square root of 42 gives approximately 6.48 meters (rounded to two decimal places).

Now that we know the length of one side, we can calculate the perimeter of the square by multiplying the length of one side by 4 (as there are four sides in a square garden).

Perimeter = 4 * Side Length

Perimeter = 4 * 6.48 meters

Perimeter ≈ 25.92 meters

Therefore, you would need approximately 25.92 meters of fencing to enclose the square garden.
