It should be 12×18. 1:3 means you take where it's at, at 1 and multiply it's size by 3.
Answer:
The dimensions of the picture after she enlarges it is:
12×18
Step-by-step explanation:
It is given that:
Heather wants to enlarge a 4 x 6 in picture using a scale factor of 1:3.
This means that the dimension of the enlarged picture will be three times the dimensions of the original picture.
i.e. one of the side will be: 4×3=12
and the other side will be: 6×3=18
Hence, the dimensions are: 12×18
