To find the area of a rectangle, we simply multiply its length by its width. Therefore, the area of the rectangle with width 8x and length 7x + 1 is:
Area = (8x)(7x + 1)
Area = 56x^2 + 8x
So the answer is B. 56x^2 + 8x.
width 8x length 7 x + ^1
Find the area of the rectangle
15x + 1
56x^2 + 8x
56x + 8
15x^2 + 9x
