Final answer:
The area of a rectangle is calculated by multiplying its length by its width. Given the length (-7 units) and width (x + 11 units), the correct area should be (-7x - 77), but this option is not provided.
Step-by-step explanation:
The subject of this question is the calculation of the area of a rectangle, a topic within mathematics, specifically, algebra. The area of a rectangle is found by multiplying its length by its width. Hence, given that the length is (1 - 8 = -7) units and the width is (x + 11) units, the expression that can represent the area is (-7)*(x + 11) which simplifies to (-7x - 77). However, this does not match any of the provided options (A, B, C, D), implying that there might be a mistake in the question or the given options.
