Find the area of the rectangle

15x + 1
56x^2 + 8x
56x + 8
15x^2 + 9x

Answer 1

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.
