Answer 18

in the first question you can use Pythagoras' Theorem which is
\[Hypotenuse = \sqrt{Opposite ^{2} + Adjacent ^{2}}\]

if u look carefully at the pic u'll see this

Answer 19

first lets find RED triangle with RED w, L, d
so your w is opposite of the triangle = 3 inches
next L is your adjacent = 12 inches
d is your hypotenuse - find it using formula i just gave you ok?

now look at black triangle
opposite is your h = 5 inches
now adjacent of this triangle is hypotenuse of your RED triangle so it'll be the answer you get for RED d [the one u just calculated]
now your hypotenuse in this BLACK triangle is the diagonal that you want, so again you the same formula and find this hypotenuse :) and it'll be your answer for Diagonal
