Answer:
Hey there!
First, we want to find the side length of the large triangle.
1/2bh=y cm^2
bh=2y cm^2
Since b and h are the same here, we have b^2= 2y, 
.
And we have FC=
.
Area of shaded triangle: 
.
This is equal to: 
, or y/4.
Let me know if this helps :)
The first four equations are correct. The remaining 4 equations are incorrect. See the attached screenshot for a detailed breakdown of why the last four equations are incorrect.
Because the number is positive
