Chris has a square garden with an area of 38.a 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 find the square root of the area because the area of a square is equal to the length of one side squared. In this case, the area is 38a m squared.

The formula to calculate the length of the side of the bigger garden is:
Length of one side = square root of the area

So, we have:
Length of one side = √(38a m²)

To find the perimeter of the smaller garden, we need to decrease the length of each side by 1.7 m.

The formula to calculate the perimeter of a square is:
Perimeter = 4 × length of one side

So, for the smaller garden, the length of one side would be (Length of one side of the bigger garden) - 1.7 m.

Substituting this value into the formula, we have:
Perimeter of the smaller garden = 4 × (Length of one side of the bigger garden - 1.7 m)

By using the given information, you can now substitute the values into the formulas and calculate the perimeter of the smaller garden.
