Answer:
Area of the rectangle  A   = 32 x - 8
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the length of the rectangle(l) = 8x-2
Given that the width of the rectangle (w) = 4
Area of the rectangle = length × width
                          A   = (8x - 2) × 4
                          A   = 32 x - 8
<u><em>Final answer</em></u>:-
Area of the rectangle  A   = 32 x - 8
