a) Hint: The area of any plane figure is proportional to the square of any of its linear measures. For similar shapes, and corresponding linear measures, the constant of proportionality is the same.
Can you now find the requested ratio?
Let's let the area of \(\triangle ACD\) be 1 unit. From part a) we can then say the area of \(\triangle ABE\) is [MATH]\frac{16}{25}[/MATH]. So, then what must be the area of trapezium \(BCDE\)?
