Question

Which of the following would result from multiplying each side of the polygon by a ratio of one-half?

The final area is twelve square kilometers

The final perimeter is twenty-four kilometers

The final area is six square kilometers

The final perimeter is twenty kilometers

Answer 1

Multiplying by a 3rd is the same as dividing by 3.

9/3=3
12/3=4
15/3=5

The area of a triangle is the (adjacent*opposite)/2

So it would be 3*4 which equals 12
12/2=6km^2, so that is correct statement.
