Answer:
No.
Explanation:
For figures to be similar, they must have proportional sides.
In other words, we can take a number and use it to scale all the sides.
The small rectangle has a 5 on the bottom side, while the big rectangle has a 15 on the bottom side. The scale factor is 3.
The small rectangle has a 3 on the right side, while the big rectangle has a 6 on the right side. The scale factor is 2.
As the scale factors are not equivalent, the figures are not similar.
