Step-by-step explanation:
we know that
To find the population density per m² of each of the above species, divide the amount of each species by the total area
so
<em>Ferns</em>

<em>Grass plants</em>

<em>Oaks Trees</em>

This isn't an ordered pair, but the slope would be 9/5 or 1.8
Step-by-step explanation:
square root 15 = irrational
square root 16 = 4 = rational
square root 21 = irrational
square root 22 = irrational
Answer:
861.56 km2
Step-by-step explanation:
the formula for the area of a trapazoid is
a= (a+b/2) + h
