Final answer:
The perimeter of a rhombus is found by multiplying the length of one side by four, thus the correct answer is B) 4 times the length of one side of John.
Step-by-step explanation:
The question "John is a rhombus. Find the perimeter of John." involves finding the total distance around the rhombus. A rhombus is a type of polygon that has four equal sides, similar to a square. Therefore, the perimeter of a rhombus, just like the perimeter of a square, is calculated by multiplying the length of one side by four. Hence, the correct answer is B) 4 times the length of one side of John. In other questions provided as references, the perimeter of a square is mentioned to be 4 times the side length, which supports the answer for the rhombus, since both shapes have equal side lengths. The analogies regarding circles and spheres, likewise, reinforce the concept that the perimeter (or circumference) of a circle is related to but not the same as the perimeter of the square that circumscribes it.
