Chris has a square garden with an area of 38.4 m squared.
He decreases the length of each side by 1.7 m to make a smaller garden.
What is the perimeter of the smaller garden. {Hint find the length of each side of the bigger garden first, then decrease the length, then find the perimeter.
To find the length of each side of the bigger garden, we need to take the square root of the area.
The area of the bigger garden is given as 38.4 m^2. Taking the square root of 38.4 gives us approximately 6.2 m.
Next, we need to decrease the length of each side by 1.7 m to find the length of each side of the smaller garden. So, the length of each side of the smaller garden will be 6.2 m - 1.7 m = 4.5 m.
Now that we know the length of each side of the smaller garden (4.5 m), we can calculate the perimeter by multiplying it by 4 since all sides of a square are equal.
Therefore, the perimeter of the smaller garden is 4.5 m * 4 = 18 m.
