Question

the length of a rectangle is x - 5. the width is x + 1. what is the area? x² - 4x - 5 2x - 4 x² + 6x - 5 none of these

Explanation:

Step1: Recall the formula for the area of a rectangle

The area \(A\) of a rectangle is given by \(A=\text{length}\times\text{width}\). Here, length \(l = x - 5\) and width \(w=x + 1\). So, \(A=(x - 5)(x + 1)\).

Step2: Use the FOIL method
