width 8x length 7 x + ^1
Find the area of the rectangle
15x + 1
56x^2 + 8x
56x + 8
15x^2 + 9x
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.
To find the area of a rectangle, you multiply its length by its width.
The given width is 8x and the length is 7x^2 + 1.
So, the area of the rectangle is:
Area = length x width
= (7x^2 + 1) x (8x)
= 56x^3 + 8x^2
Therefore, the correct answer is 56x^3 + 8x^2.
