Answer:
19596.74 yd ^ 2
Step-by-step explanation:
The first thing is to detect the data they give us, that value corresponds to the perimeter.
The perimeter has how it formulates:
p = 2 * pi * r
solving for r
r = p / 2 * pi
replacing
r = 496.12 / (3.14 * 2)
r = 79 and d
now the area is equal to:
a = pi * r ^ 2
replacing
a = 3.14 * 79 ^ 2
a = 19596.74 and d ^ 2
means that the area is 19596.74 yd ^ 2
Using proportion...

length of barn's shadow length of tree's shadow
20 x
---- = ---
12 8
Using cross-multiplication...
20 x 8 = 12x
160 = 12x
x = 13 1/3 or 13.3333
The tree is 13 1/3 meters long.
