Answer 1

31 in

Explanation:

First let's split the bottom part of the L in two parts of 19 and
`26-19=7 in` each. Now the whole area is made of two rectangles of sides
`19*11` and
`7* h`,where h is the length of the left side. These two have to add up to 426 so

`19* 11 + 7* h = 426\\209+7h = 426\\7h =217 \rightarrow h=31`
