I apologize for the confusion in my previous response. Let's correct that.

1. The area of the rectangle is calculated by multiplying the length and width.
Area = (9.3 × 10^2 cm) * (8.1 × 10 cm) = (9.3 * 8.1) × (10^2 * 10) = 75.33 × 10^3 cm^2 = 7.533 × 10^4 cm^2

This statement is True.

2. The perimeter of the rectangle is given by the formula 2(length + width).
Perimeter = 2(9.3 × 10^2 + 8.1 × 10) = 2(9.3 * 10^2 + 8.1 * 10) = 2(93 + 81) × 10 = 2(174) × 10 = 348 × 10 = 3.48 × 10^3 cm

This statement is True.

3. The length of the rectangle is approximately 1.15 × 10 times greater than the width.
Length to Width ratio = (9.3 × 10^2) / (8.1 × 10) = (9.3 / 8.1) × (10^2 / 10) = 1.148 × 10

This statement is also True.

4. The length of the rectangle squared is calculated by squaring the length.
Length Squared = (9.3 × 10^2)^2 = (9.3)^2 × (10^2)^2 = 86.49 × 10^4
This simplifies to 8.649 × 10^6

Therefore, the correct answers are:
True
True
True
True
