I have this problem could someone help me with it? Here it is.
Triangle DEF (not shown) is similar to triangle ABC shown, with angle B congruent to angle E and angle C congruent to angle F. The length of side DE is 6 cm. If the area of triangle ABC is 5 square centimeters, what is the area of triangle DEF? Side AB (which is congruent to DE) of triangle ABC is 2 cm (not the base side and the height isn't shown).
There is an image of triangle ABC in my book, sorry I can't show it to you. I just need to know what formula to use on this kind of problem.
Thanks!
