The UK has an area of 243,610km2 and a population of 6.41 x 107. Calculate the population density the United Kingdom. Answer to

hodyreva [135]

Answer: Population density the United Kingdom $=2.63\times10^2$

A= 2.63

B= 2

Step-by-step explanation:

We know that, to calculate the population density, we will divide the population by the size of the area.

i.e. $\text{Population density}=\dfrac{\text{Population size}}{\text{Area}}$

Given : Area of UK = 243,610 km²1

Population = $6.41 \times 10^7$

Then, the population density the United Kingdom would be :

$\text{Population density}=\dfrac{6.41 \times 10^7}{243,610}\\\\=\dfrac{64100000}{243610}=263.125487459\\\\\approx263=2.63\times10^2$

On comparing to $A\times10^B$ , we get

A= 2.63

B= 2
