Answer:
<u>A) 19.66 people/km²</u>
Step-by-step explanation:
<u>Given</u>
- Area of the continent = 1.78 x 10⁷ km²
- Population = 3.5 x 10⁸ people
<u>To Find</u>
<u>Solving</u>
- population density is the number of people per unit area
- pd = people / area
- pd = 3.5 x 10⁸ / 1.78 x 10⁷
- pd = 1.966 x 10
- pd = <u>19.66 people/km²</u>
The kite area can be calculated using the formula
a = 1/2 × d₁ × d₂
with d₁ as first diagonal and d₂ as second diagonal
From the question, we know that
d₁ = 9.5 + 9.5
d₁ = 19 in
d₂ = 7 + 12
d₂ = 19 in
Calculate the area by plugging in the numbers into the formula
a = 1/2 × d₁ × d₂
a = 1/2 × 19 × 19
a = 1/2 × 361
a = 180.5
The area of the kite is 180.5 in²
The answer is fourth answer
