Threatened monarch butterflies are monitored by measuring the area occupied by overwintering butterflies in Mexico. According to
Pani-rosa [81]

Answer:

14.2 hectares

Step-by-step explanation:

Fund Mexico, monarch butterflies occupied 1.13 hectares one recent winter, and 4.01 hectares the following winter (one year later)

The formula of Geometric growth

(Pt/ Po)^1/t

Where Pt = Size after t years = 4.01 hectares

Po = Initial size = 1.13

t = times = 1

=( 4.01/1.13 )^1/1

= 3.5486725664

Hence, Geometric growth rate = 3.5486725664.

It's size in hectares after another 1 year = Current size in hectares × Geometric growth rate

= 4.01 ×3.5486725664

= 14.230176991 hectares

≈ 14.2

The centre point is given by;
( \frac{ x_{2}+ x_{1}  }{2} , \frac{ y_{2} + x_{1} }{2} )
=(  \frac{4+4)}{2}  + \frac{-4+(-6)}{2} )
=( \frac{8}{2} , \frac{-10}{2} )
