4i. An ostrich weighs about 120 kg when alive. Its wing is
38 cm long and 30 cm wide at the base. Assuming the wing to
be a right triangle, compute the wing-loading (kg per square cm of
wing surface) of an ostrich. (Remember it has two wings.)
Compare this with a stork, which is a moderately large, walking,
flighted bird, which may weigh as much as 5 kg. Its wing
measures 86 cm long by 30 cm wide at the base.

If the ostrich needs the same wing loading as the stork to
fly, how long would its wings need to be (assume that the width of
the wing is 30 cm)?
