The equation for the perimeter is P = 5n + 7. The perimeter P is equal to the length of a side of one triangle multiplied by the number of triangles in the figure n plus the length of the base. The equation for the perimeter is P = 7n + 5. The perimeter P is equal to the length of a side of one triangle multiplied by the number of triangles in the figure n plus two times the length of the base. The equation for the perimeter is P = 7n + 10. The perimeter P is equal to the length of the base of one triangle multiplied by the number of triangles in the figure n plus two times the length of another side. The equation for the perimeter is P = 5n + 14.
