Question

Write an expression to represent the area of the following figure.

Answer 1

Answer:

$x^2 - 12x$

Step-by-step explanation:

The given rectangle had a length (l) of (x - 12), and a width (w) of x.

Area of rectangle = $l * w$

Therefore, the expression representing the are if the given rectangle is:

$Area_{rectangle} = (x - 12)*x$

$Area_{rectangle} = x*x - 12*x$

$Area_{rectangle} = x^2 - 12x$

The expression for the area = $x^2 - 12x$
