Answer: C. 24 ft
Step-by-step explanation: You can simply divide 1 1/2 inches by 1/4 to find how many times the 1/4 margin fits into the kitchen floor plot.
1 1/2 = 3/2, and any fraction divided by another fraction is the same as multiplying the reciprocal, so 3/2 * 1/4 = 3/2 *4/1. The result is 12/2, or 6.
You know that every 1/4-inch margin is 4 feet in actual length, so you can multply 6 (the number of 1/4-inches) to 4 feet and you get 24 feet.
