Dorado County, which has a population of about 6,720, is divided into 4 townships. About 1/4
Ostrovityanka [42]
Density of population = total population / area of the township

Emerson township:
Population of Emerson = 6720 * (1/4)
= 1680
Density of population = 1680 /344
= 5 per square miles

Franco township:
30% of 1680 = 0.3 * 1680 = 504
Population = 1680 + 504
= 2184
Density = 2184/512
= 4 per square mile

Answer:

A = 22.5 m²

Step-by-step explanation:

longest side length

b = √((-7 + 4)² + (-1 - 8)²) = √90

other sides

a = √((-1 + 7)² + (2 + 1)²) = √45

height

h = √((√45)² - (½√90)²) = √22.5

Area of triangle

A = ½bh = ½√90√22.5 = 22.5 m²

a little math shows that this triangle is a tilted half of a square with sides √45
