12345 [234]
To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2

jeyben [28]

Answer:

13, 587 times

Step-by-step explanation:

Population of City A  

= 1.9 * 105 = 157.5

Population of City B

= 1,070,000

Population of City C

=  2 * city B

=  2 * 1,070,000

= 2,140,000

The population of City C is how many times the population of City A?

City C = x * City A

2,140,000 = x * 157.5

x = 2,140,000 / 157.5

x = 13587.30

The population of City C is 13587.30 times the population of City A.

Hope this helps :)
