$\bf \begin{cases}
s=\textit{Asia's population}\\
a=\textit{Africa's population}\\
r=\textit{rest of the world}\\
----------\\
\boxed{s}=a+2\\
\boxed{r}=\frac{s}{2}+0.2
\end{cases}\implies 
\begin{array}{llll}
s+a+r=6.7\\\\
\boxed{a+2}+a+\boxed{\cfrac{s}{2}+0.2}=6.7\\\\
a+2+a+\cfrac{\boxed{a+2}}{2}+0.2=6.7
\end{array}$

solve for "a", to see what Africa's population will then be

Rectangle A has length 12 and width 8. Rectangle B has length 15 and width 10. Rectangle C has length 30 and width 15.

Anna007 [38]

Answer:

yes; 1.25

Step-by-step explanation:

The length to width ratios of the rectangles are ...

A: 12/8 = 1.5

B: 15/10 = 1.5

C: 30/15 = 2.0

Rectangles A and B have the same aspect ratio, so are similar. Rectangle B is a scaled copy of A with a scale factor of 10/8 = 1.25.
