Answer:
[tex]16x^2 + 18y[/tex] units
Step-by-step explanation:
The perimeter of a rectangle is [tex]2l+2w[/tex], where l and w are the length and width respectively. Since we know the value of the length and width, we can substitute inside the equation.
[tex]2(x+5y) + 2(8x^2 - x + 4y)\\\\2x + 10y + 16x^2 - 2x + 8y[/tex]
We can now combine like terms to get [tex]16x^2 + 18y[/tex].
Hope this helped!
