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. 16x² 4x 4x² (x + 4)²

Explanation:

Step1: Define length in terms of width

Given width = $x$, length = $4x$ (since length is 4 times width).

Step2: Use area formula for rectangle

Area of rectangle $A =$ length $\times$ width. Substitute length = $4x$ and width = $x$ into formula: $A=4x\times x = 4x^{2}$.

Answer:

C. $4x^{2}$
