There isn't a capital of Kingston, as it is a capital itself. It's the capital of Jamaica.
Area of the square garden = 30.25 square feet
Let us assume each side of the square garden = a
Then
a^2 = 30.25 square feet
a = 5.5 feet
Now
Perimeter of the square garden = 4a
= 4 * 5.5 feet
= 22 feet
So the perimeter of the garden is 22 feet.
