Question

8 multiple choice 1 point the length of a rectangle is 4 times its width. write an expression for the area of the rectangle. let x be the width of the rectangle. \\( (x + 4)^2 \\) \\( 4x \\) \\( 16x^2 \\) \\( 4x^2 \\)

Explanation:

Step1: Define length of rectangle

Let width = $x$, so length = $4x$.

Step2: Apply area formula

Area = length $\times$ width = $4x \times x = 4x^2$.

Answer:

$4x^2$ (the last option)
