What is the base area of Box 3?

Answer 1

x² + 4x

Explanation:

The area (A) of the base is

A = length × width

= x(4 + x) = 4x + x² = x² + 4x

Answer 2

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

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}* \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`.
