11-82.

$\frac{1}{2} (base)(height)$

Area A = 72 un2
Area B = 40.5 un2

Find the ratio between one of the pairs of
corresponding sides for the two triangles.

$\text{Use \frac{6}{8} or \frac{13.5}{18}}.$

What do you get after simplifying?

$\frac{3}{4}$

How can you change the scale
factor to get this area ratio?

$\frac{40.5}{72} = \frac{9}{16}$
