Question

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 the nearest whole person and give your answer in standard form, such as a x 10b where you are required to enter the values of A and B

A =

B =

Answer 1

Answer: Population density the United Kingdom
`=2.63*10^2`

A= 2.63

B= 2

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}=\frac{\text{Population size}}{\text{Area}}`

Given : Area of UK = 243,610 km²1

Population =
`6.41 * 10^7`

Then, the population density the United Kingdom would be :

`\text{Population density}=(6.41 * 10^7)/(243,610)\\\\=(64100000)/(243610)=263.125487459\\\\\approx263=2.63*10^2`

On comparing to
`A*10^B`, we get

A= 2.63

B= 2
