Question

Anyone know the answer ?

Answer 1

The area of the rectangle will be:

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

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)* \:3x^3+\left(6x^3\right)* \: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`
