To find the area of a rectangle, you multiply the length by the width.
The length of the rectangle is given as 7x + 1 and the width is given as 8x.
Therefore, the area of the rectangle is (7x + 1) * 8x.
To simplify this expression, you can distribute the 8x to both terms in the parentheses:
8x * 7x + 8x * 1 = 56x^2 + 8x.
Therefore, the correct answer is B) 55x^2 + 8x.
