Question

(PLEASE HELP ASAP)What is the base area of Box 3?

Answer 1

Answer:

$\text{Base area of box 3}=x^2+4x$

Step-by-step explanation:

We are asked to find the base area of the box 3.

We know that base area of box or cuboid can be calculated by multiplying its base length and width.

$\text{Base area of box 3}=\text{Length}\times \text{Width}$

$\text{Base area of box 3}=(4+x)*x$

Use distributive property $a(b+c)=ab+ac$:

$\text{Base area of box 3}=4x+x^2$

$\text{Base area of box 3}=x^2+4x$

Therefore, the base area of box 3 would be $x^2+4x$.

Answer 2

Answer:

x² + 4x

Step-by-step explanation:

The area (A) of the base is

A = length × width

   = x(4 + x) = 4x + x² = x² + 4x
