Hello there !

Regarding number 3, suppose the entirety of the length of the big rectangle, including 1,2 and3, being $$x$$. Use $$k$$ to find the ratio of the lengths, and then calculate the length of each rectangle with x. Then, equalize des areas and isolate for $$x$$.

Regarding number 8, find the measurement of $$AC$$ with trigonometric identities to afterwards use the $$k$$ ratio to find the sides of the triangle. Or, you could directly calculate the area and use $$k^{2}$$.
