Answer 1

Answer:

The perimeter of ABC is 36 feet

Step-by-step explanation:

ABC is Similar/in ratio to DEF.

Using the side BC, we can tell that it is corresponding to side EF.

This makes the ratio between the two sides 15:5 or, 3:1

This means that the ratio of ABC and DEF's perimeters is 3:1 feet

Because we know the perimeter of DEF-12 ft- We can substitute this number in the ratio which means that 3(12):12 is the ratio of the perimeters

This means that the perimeter of ABC is 3*12, or 36 feet
