Answer:
x² + 4x
Step-by-step explanation:
The area (A) of the base is
A = length × width
= x(4 + x) = 4x + x² = x² + 4x
Answer:
[tex]\text{Base area of box 3}=x^2+4x[/tex]
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.
[tex]\text{Base area of box 3}=\text{Length}\times \text{Width}[/tex]
[tex]\text{Base area of box 3}=(4+x)*x[/tex]
Use distributive property [tex]a(b+c)=ab+ac[/tex]:
[tex]\text{Base area of box 3}=4x+x^2[/tex]
[tex]\text{Base area of box 3}=x^2+4x[/tex]
Therefore, the base area of box 3 would be [tex]x^2+4x[/tex].
