Hi, I need help with this math question .

Find the required measurements of the following trapezoids. a = 8 cm b = 16 cm h = 10 cm

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

According to the data set, where should the upper quartile line of the box plot be placed?
