Essay

Suppose triangle ABC is similar to triangle DEF with AB = 6, BC = 5, AC = 7, and DE = 10, all in centimeters. Assume $\angle A = \angle D , \angle B = \angle E , \angle C = \angle F$
A) Find the lengths of DF and EF.
B) If the area of triangle ABC = about 15 cm², what is the area of triangle DEF? Justify your answer.
