Let's recall the formula for getting the area of a square:


\text{ Area = s}^2

Given,

s = x - 5

To get the expression that best represents the area of the square, let's substitute the value of s in the formula.


\text{ Area = s}^2
\text{ Area = (x}-5)^2\text{ = (x - 5)(x - 5)}
\text{ Area = x}^2-5x-5x+25=x^2\text{ - 10x + 2}5

Therefore, the answer is letter D.
