Final answer:
To find the area of the unshaded part of the rectangle, we need to subtract the area of the shaded part from the total area of the rectangle. Since we don't have the dimensions of the shaded part, we can't calculate its area and determine the area of the unshaded part.
Step-by-step explanation:
To find the area of the unshaded part of the rectangle, we need to subtract the area of the shaded part from the total area of the rectangle. Let's call the length of the rectangle 'l' and the width 'w'. The total area of the rectangle is given by the formula A = l x w. If we know the dimensions of the shaded part, we can calculate its area and subtract it from the total area.
Since we don't have the dimensions of the shaded part, we can't calculate its area and determine the area of the unshaded part. Therefore, we cannot determine the correct answer from the given options.
