Answer:

F. 8%

Explanation:

The formula of an area of a rectagle:

A=wl

w - width

l - length

The large rectangle:

w = 5, l = 5

$A_L=5\cdot5=25$

The small rectangle:

w = 1, l = 2

$A_S=1\cdot2=2$

Calculate what percentage of the area of a large rectangle is a small rectangle.

Method 1:

$(2)/(25)\cdot100\%=2\cdot4=8\%$

Method 2:

$\begin{matrix}25&-&100\%&\text{divide both sides by 25}\\\\1&-&4\%&\text{multiply both sides by 2}\\\\2&-&8\%\end{matrix}$
