We cannot determine the area of the rectangle without knowing the measurements of its length and width. The answer is not provided in the given options.
Find the area of the rectangle. rectangle 7x + 1 by 8x
1. 15x+1
2. 56x^2+8x
3. 56x+8
4. 15x^2+9x
The formula for the area of a rectangle is A = length x width. Substituting the given values, we get:
A = (7x+1) x (8x)
A = 56x^2 + 8x
Therefore, the answer is option 2: 56x^2 + 8x.
