Question

The dimensions of the base of Box 1 are x by 3x. The base area of Box 1 is

Answer 1

Answer:

3x^2

Step-by-step explanation:

Area is length times width of a side of the box. Base of box 1 is 3x by x. 3x times x equals 3x squared. We don't have any more information, so x remains a variable.

Answer 2

Answer:

The area is: $A = 3x ^ 2\ units ^ 2$

Step-by-step explanation:

We assume that the base of Box 1 is a rectangle of sides x and 3x.

So by definition the area of a rectangle is:

$A = Lw$

Where: L is the length and w is the width of the rectangle

So the base area of the Box 1 is:

$A = 3x * x$

$A = 3x ^ 2\ units ^ 2$
