Question

What is this??? can anyone help?​

Answer 1

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}`
