<h3>Answer:</h3>

A(x) = x(16 -x)

<h3>Step-by-step explanation:</h3>

Area is the product of length and width. If the length is x, then the width will be half of the total perimeter less the two sides of length x, (32-2x)/2 = 16-x.

So, the area is ...

... A = length · width

$logM^p=p*logM$ (This is true)

You can observe in Option B:

$logM+logN=log(MN)$ (This is true)

You can observe in Option C:

$logM-logN=log(M-N)$ (This is not true)

You can observe in Option D:
