Above are two different models of the same triangle. If the area of the model on the left is 23 sq cm, what is the area of the model on the right?
A.
92 sq cm
B.
25.5 sq cm
C.

D.
46 sq cm

 

Answer 1

The answer must come from the SQUARE of the similarity ratio.  E.g. if all the sides of one triangle are k times the sides of another triangle, then the corresponding ratio of their areas is k².  But obviously we need to SEE or BE TOLD what that is. Do not omit necessary figures ( or their complete descriptions) in Geometry problems!
