Why does Robert Frost allude to Eden in "Nothing Gold Can Stay"?

Eden's short-lived perfection is similar to the temporary perfection of nature's first green.

Eden is a place that remained perfect forever, just like the world described in Frost's poem.

Eden is known to be filled with gold.

Eden is a place that Frost visited many times.

Eden's short lived perfection is similar to the temporary perfection of nature's first green.

Explanation: Robert Frost used the biblical reference of the Garden of Eden  to emphasize his point of the fact that nothing stays perfect forever.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172
