(a).
S(shaded) = S(big triangle) - S(small triangle)
(b).
As the ratio of the sides of small triangle to big triangle is k, we have S(small triangle)/S(big triangle) = k^2. Apply that to A.
(c).
Substitute the values into the formula you got in (b).

yeah except im not sure how to even find d^2 in terms of c b and k

d^2? There is no d here, let alone d^2.
First, what's the area of ABC?

there are no values
like numjbers
area of a triangle is 1/2bh
so probably 1/2*b*c
hasty igloo
so probably `1/2*b*c`
Yes. S(ABC) = (1/2)bc.
Now, as S(XYZ)/S(ABC) = k^2, what is S(XYZ)?
hasty igloo
why are you dividing S(xyz) by s(abc)
If the ratio of linear sizes of triangles is k, then the ratio of their areas is k^2.

You're welcome!

You're welcome!
do you mind helping me with 9b) please?
