F. How many times greater is the area of triangle DEF than the area of triangle ABC? Show/explain.

Area of ΔDEF is 2.25 times the area of ΔABC.

Step-by-step explanation:

Since, ΔDEF is the enlarged form of ΔABC,

Scale factor =

                    =

                    = 1.5

Since, ratio of the areas of image and preimage triangles = (Scale factor)²

= (Scale factor)²

Area of image ΔDEF = 2.25(Area of ΔABC)

Therefore, area of ΔDEF is 2.25 times the area of ΔABC.

it's both, now can you answer my most recent question?
