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 \( k^{2} \).
