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.
no way to tell the perimeter from just the area.
All we know is that the smaller dimension is greater than 1.7 m.
To find the length of each side of the larger garden, we can take the square root of the area, since we know that the area of a square is the side length squared.
Let's calculate the length of each side of the larger garden.
√(Area of the larger garden) = √(38.4 m²)
= 6.2 m (approximately)
Now, let's calculate the length of each side of the smaller garden by decreasing the length of each side by 1.7 m.
Length of each side of the smaller garden = Length of each side of the larger garden - Decrease in length
= 6.2 m - 1.7 m
= 4.5 m
Now that we know the length of each side of the smaller garden is 4.5 m, we can find the perimeter of the smaller garden by multiplying it by 4 (since all sides of a square are equal).
Perimeter of the smaller garden = 4 * Length of each side of the smaller garden
= 4 * 4.5 m
= 18 m
Therefore, the perimeter of the smaller garden is 18 meters.
