EXPLANATION
The given product is

This is always equal to

The identity

is called difference of two squares.
We can verify this by simply expanding the brackets using the distributive property to obtain,


This simplifies to
Easy multiply 1/16 by any number in example 1*2=2——16*2=32 therefore 1/16=2/32

You didn't include a picture of the answer choices, but this is what the answer would look like. Pretend the different shapes represent different rows:

There are three rows. 4 Books in each row.
X = width. the perimeter of a rectangle is 2*length + 2*width, so the perimeter of this rectangle is 2x + 2(5x) = 72. distribute the two to get 2x + 10x = 72. so 12x = 72. divide by twelve to get x = 6. the width is six, so the perimeter (5x) is 30. the area of a rectangle is length times width, 30*6, so the area is 180 m.
