Question

what's the simplest form to represent the area of a rectangular building that's 2y feet and the length to be 9y-4

Answer 1

The area of a rectangle is given by the formula:

`A=lw`

Where

A is area

l is length

w is width

We find the expression for the area by multiplying the two "lengths" given:

`\begin{gathered} A=2y(9y-4) \\ A=18y^2-8y \end{gathered}`

The answer is:

`A=18y^2-8y`
