What is the perimeter of a figure made up of seven regular hexagons, each with a perimeter of 18?

To find the perimeter of a figure made up of seven regular hexagons, it's important to first understand the perimeter of each hexagon. Given that each hexagon has a perimeter of 18, you can calculate the total perimeter by multiplying the number of hexagons by the perimeter of one hexagon.

If you have seven hexagons, you would multiply the number of hexagons (7) by the perimeter of one hexagon (18):

7 x 18 = 126.

The total perimeter of the figure made up of these seven hexagons is 126.

This calculation reflects how the overall perimeter of a composite shape is determined by its individual components. Since hexagons share sides with one another when arranged together, you might initially think you could simply add up their perimeters, but it’s important to consider the context of how they are arranged. However, in the case of non-overlapping hexagons, this simple multiplication accurately reflects the perimeter calculation.

Therefore, 126 is the correct answer, as it takes into account the total perimeter contributed by all the hexagons combined.
