h(r) = 69.09 + 2.24r

h(42) = 69.09 + 2.24(42)

h(42) = 69.09 + 94.08

h(42) = 163.17

The height of the man is roughly 163.17 cm tall (note: 163.17 cm = 64.2402 inches = 5 feet, 4.2402 inches, all approximations)

Predict the height of a man whose femur is 42 cm long.
-----------------
h(42) = 69.09 + 2.24*42 = 163.17 cm
