A rectangle has length 9.3×102cm and width 8.1×10cm. Which of these statements are true? (4 points)
1. The area of the rectangle is 7.533×10^4 cm^2.
2. The perimeter of the rectangle is 1.71×10^3 cm
3. The length of the rectangle is approximately 1.15×10
4. times greater than the width
5. The length of the rectangle squared is approximately 8.65×10^5
1. True - The area of the rectangle is calculated by multiplying the length and width, so 9.3×10^2 cm * 8.1×10 cm = 7.533×10^4 cm^2.
2. True - The perimeter of a rectangle is calculated by adding two times the length and two times the width, so 2*(9.3×10^2 cm) + 2*(8.1×10 cm) = 1.71×10^3 cm.
3. False - The length of the rectangle is 9.3×10^2 cm, not 1.15×10.
4. False - The length of the rectangle is not approximately 1.15 times greater than the width.
5. True - Squaring the length would result in (9.3×10^2 cm)^2 = 8.65×10^5 cm^2.
