Question

Anyone know the answer ?

Answer 1

Answer:

The area of the rectangle will be:

$A=18x^6+48x^5+6x^4$

Step-by-step explanation:

Given

• height or length = l = 6x³

• width = w = 3x³+8x²+x

We know that Area of the rectangle

A=wl

  = (3x³+8x²+x) × (6x³)

  $=\left(6x^3\right)\times \:3x^3+\left(6x^3\right)\times \:8x^2+\left(6x^3\right)x$

  $=3x^3\left(6x^3\right)+8x^2\left(6x^3\right)+x\left(6x^3\right)$

  $=18x^6+48x^5+6x^4$

Thus, the area of the rectangle will be:

$A=18x^6+48x^5+6x^4$
