A rectangle has length 9.3 × 10? cm and width 8.1 x 10 cm. Which of these

Question

statements are true? (4 points)

The area of the rectangle is 7.533 x 10^4 cm^2? True or False

The perimeter of the rectangle is 1.71 × 10^3 cm True or False

The length of the rectangle is approximately 1.15 x 10 times greater than the width

The length of the rectangle squared is approximately 8.65 x 10^5 True or False

Answer 1

The area of the rectangle is 7.533 x 10^4 cm^2 - True

The perimeter of the rectangle is 1.71 × 10^3 cm - False (perimeter = 2(length + width) = 2(9.3 x 10 + 8.1 x 10) = 2(17.4 x 10) = 34.8 x 10 = 3.48 x 10^3 cm)

The length of the rectangle is approximately 1.15 x 10 times greater than the width - True (9.3 x 10 / 8.1 x 10 = 1.15)

The length of the rectangle squared is approximately 8.65 x 10^5 - False (9.3 x 10)^2 = 86.49 x 100 = 8.649 x 10^3, not 8.65 x 10^5
