Need help. I do not know what to do for this question .

So we can use the fact that they are both similar triangles which means we can work out the scale factor of their lengths. We know that 7+9 is 16 so the ratio of their areas will be 7/16 to 9/16. If we square root 9/16 this gives us a side length of 3/4 for the base of the triangle (not including the trapezium). Now we know their is a length of 4 from then origin to the last point on the triangle (-4,0) which can also be written as
Spoiler:

16/4
. And we know the length 3/4 is just 3/4 of the entire base of the whole triangle so we can work out 3/4 of the length. Can you take it from there?
