Answer 1

Answer:

The answer to the 1st question "The base area of Box 1 is..."

B.   3x2

The answer to the 2nd question, "The dimensions of the base of Box 2 are x by 4x − 1." is..

Step-by-step explanation:

Answer 2

The base area of box 1 is $3x^2\ square\ units$

Solution:

Given that,

The dimensions of the base of Box 1 are x by 3x

Length = x

Width = 3x

To find: base area of box 1

The base area is given as:

$base\ area = length \times width\\\\base\ area = x \times 3x\\\\base\ area = 3x^2$

Thus base area of box 1 is $3x^2\ square\ units$
