542. One third

Easy Medium Hard Extreme

Rectangle A is one third of the size of rectangle B with 6 and 14 matchsticks used in A and B respectively.

Transfer 1 matchstick from B to A which means you now have 7 matchsticks in A and 13 matchsticks in B. Create 2 new shapes, not necessarily rectangles, with shape A still one third of the size of shape B.
