Question

The perimeter of a rectangular garden is 346. if the width of the garden is 79 feet, what is its length?

Answer 1

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
