Question

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

Answer 1

3x^2

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

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

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`
