Question

ABC DEF. The area of ABC is given. Find the area of DEF

Answer 1

Answer: B

Step-by-step explanation:

The ratio of the areas of similar figures is the square of the scale factor.

• Scale factor = image/preimage = 48/12 = 4.

So, the ratio of the areas is 16, and thus the area of DEF is (16)(90)=1440
