Would multiple average rulers be necessary to measure the length of a giant armadillo?

No, multiple average rulers would not be necessary to measure the length of a giant armadillo. The average ruler is 12 inches or 30 centimeters in length. The typical length of the giant armadillo is 75–100 cm (30–39 in), with the tail adding another 50 cm (20 in), so one ruler would be sufficient to measure the length of a giant armadillo.
