Considering the area and the perimeter of a square, we have that:
a. The length of each side is of 4x.
b. The perimeter of the garden is of 16x.
c. The new perimeter would be of 16x + 20.
For a square of side length s, we have that:
For this problem, the area of the garden is 16x², hence the length of each side is found as follows:
s² = 16x²
s = sqrt(16x²)
s = 4x.
The length of each side is of 4x.
Then the perimeter of the garden as found as follows:
P = 4s = 4(4x) = 16x.
The perimeter of the garden is of 16x.
If each side was increased by 5 feet, the new side length would be of:
s = 4x + 5.
Hence the perimeter would be:
P = 4s = 4(4x + 5) = 16x + 20.
The new perimeter would be of 16x + 20.
