A rectangular bandage measures 5cm by 8cm. What is the area covered by the bandage?
- A. 10cm
- B. 13cm
- C. 40cm^2
- D. 64cm^2
Correct Answer: D
Rationale: Rationale:
To find the area of a rectangle, you multiply the length by the width. In this case, the length of the bandage is 8cm and the width is 5cm.

Area = 8cm x 5cm
Area = 40cm^2
Therefore, the area covered by the bandage is 40cm^2.
Solve for x: 120:x::40:0.5.
- A. 1.5
- B. 60
- C. 0.167
- D. 16
Correct Answer: A
Rationale: To solve the proportion 120:x::40:0.5, cross-multiply to get 120 * 0.5 = 40 * x. This simplifies to 60 = 40x. Dividing both sides by 40 gives x = 1.5. Therefore, the correct answer is A. Choice B (60) is incorrect because x is not equal to 60. Choice C (0.167) is incorrect as it does not result from solving the proportion. Choice D (16) is also incorrect because x is not equal to 16.
