sub
b + 8
b - 8
8b
b/8

Explanation:

Step1: Recall the area formula of a rectangle

The area formula of a rectangle is \(A = \text{base}\times\text{height}\). Here, the base is \(b\) and the height is \(8\), so the area \(A=8\times b = 8b\).

Step2: Substitute \(b = 10\) into the area formula

When \(b = 10\), we substitute \(b\) into \(A = 8b\). Then \(A=8\times10=80\).

Answer:

The expression that represents the area of this rectangle is \(8b\). When \(b = 10\), the area of the rectangle is \(80\) square units.
