Step-by-step explanation:
The most important principle in designing an efficient kitchen is that the work areas should be arranged in a triangular pattern. This is known as the kitchen work triangle and is a concept that optimizes the flow of work between the three main kitchen work areas: the sink, the stove, and the refrigerator.
