If Benny is 12 right now, that means that he is twice his sisters age because he is 200% of or 2 times his sister's age. His sister right now is 6 years old then.
After 4 years, Benny will be 16 (add 4 to 12) and his sister will be 10.
To find the percentage,divide his age by his sister's age and make it a percentage.
16/10=1.6=160%
Hope this helps.

, so the answer would be A
Step-by-step explanation:

The area of the rectangle can be found by multiplying the width by the height, so the equation would be

The area of the the triangle can be found by the formula 
This means that the equation would look like

Now that we have both the area of the triangle and the rectangle, we can create a ration of the area of the triangle to that of the rectangle. It would look like this

This would simplify to
