Martin’s bed is 7 feet in length. Which of the following represents the length of the bed, in centimeters?
A. 209.42 cm B. 213.36 cm C. 215.52 cm D. 217.94 cm
Explanation: Since 7 feet equals 84 inches, and 1 inch equals 2.54 centimeters, the following proportion can be written: 84/x = 1/2.54. Solving for x gives: x=213.36. Thus, the bed is 213.36 centimeters in length.
