Answer:
20 inches by 28 inches
Step-by-step explanation:
The current size of the picture is 5 inches by 7 inches
If we want to enlarge the picture by a factor of 4, the perimeter will also increase by the factor of 4.

= 20 inches by 28 inches
Hence, the size of the enlarged picture is 20 inches by 28 inches.
