I didn't get all the part with the tiles, but here's the general answer:
given a polynomial
we have that is a factor of
if and only if k is a root of
, i.e. if
So, given the polynomial
We can check if is a factor by evaluating
:
So, is not a factor.
Similarly, we can evaluate to check if
are factors:
So, only is a factor of

Explanation:
We're given the height in relation to base BC, so we need to find the length of this base. This is the same as finding the distance from B to C.
Turn to the distance formula
Coincidentally, the base and height are the same. This won't always be the case.
Now we can find the area of the triangle
The area of the triangle is 1 square unit.
See diagram below.
