Question

a rectangular window has a length of 12 ft and a width of x ft. which expression represents the area of the window?
○ $\frac{12}{x}$
○ $6x$
○ $12x$
○ $x + 12$

Explanation:

Step1: Recall area formula

The area formula for a rectangle is $A = l\times w$, where $l$ is length and $w$ is width.

Step2: Substitute given values

Given $l = 12$ ft and $w=x$ ft. Substituting into the formula, we get $A=12\times x = 12x$.

Answer:

C. $12x$
