Answer:
A=[tex]8w^2+5w[/tex]
Step-by-step explanation:
We are given that John is building a rectangular pen for his sheep.\
We have to complete the given equation
Let w be the width of rectangular pen
According to question
Length of pen=8w+5
We know that
Area of rectangle=[tex]Length \times breadth[/tex]
Using the formula
Area of rectangular pen=[tex]w(5+8w)=8w^2+5w[/tex]
Therefore, the area of rectangular pen=A=[tex]8w^2+5w[/tex]
