he study of size and shape is called "allometry," and many allometric relationships involve exponents that are fractions or decimals. For example, the body measurements of most four-legged animals, from mice to elephants, obey (approximately) the following power law: Average body thickness = 0.4(hip-to-shoulder length)3/2 where body thickness is measured vertically and all measurements are in feet. Assuming that this same relationship held for dinosaurs, find the average body thickness of the following dinosaur, whose hip-to-shoulder length can be measured from their skeleton. (Round your answer to one decimal place.) a dinosaur whose hip-to-shoulder length was 9 feet.
