The perimeter of a rectangular garden is 346. if the width of the garden is 79 feet, what is its length?
Nostrana [21]
Perimeter = L + L + W + W
346 = L + L + 79 + 79
346 = L + L + 158
346 - 158 = L + L  158 -158
188 = L + L
So im gonna square root 188
188 ( square rooted) = 13.7113092.....
Im gonna round it so the lengths gonna be 
≈ 13.7

where

(h,k) is the center of the circle

r is the radius of the circle

substitute the given vales

(x+15)^2+(y-11)^2=2^2

(x+15)^2+(y-11)^2=4
