Answer:
So basically, since the formula is 2(l × w), we will do:
(Length) 2/5 + 2/5 (the same thing as multiplying it by two) which equals 4/5.
Then we do the same for the width:
(Width) 1/5 + 1/5 (also the same thing as multiplying by two) to get 2/5.
Now we just add both fractions: 4/5 + 2/5 = 1 1/5
So the answer is C.

Answer:
Dilate Circle A by a scale factor of 3
Step-by-step explanation:
Circle A has a radius of 3, Circle B has a radius of 9. By dilating Circle a by a scale factor of 3, it will make it the same size as Circle B, showing that the two circles are similar.
Rotating and reflecting does nothing because both circles are in the same quadrant and rotating a circle does nothing to the placement.
Translating the circle (x+3, y-2) does not put it in the same place as circle B.
