Question

What is this??? can anyone help?​

Answer 1

Answer:

F. 8%

Step-by-step 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:

$\dfrac{2}{25}\cdot100\%=2\cdot4=8\%$

Method 2:

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