Answer:
Area= 76.5 cm²
Explanation:
First, we have to find the ratio of the sides. The ratio of the corresponding sides is 13.5/9= 1.5
Then we have to find the ratio of the area which is 2.25 as the area has a square in their unit and the square of 1.5 is 2.25.
Next, to find the DEF we have to multiply the ratio of area with the area of ABC.
A= 2.25 × 34
A= 76.5 cm²
