Answer:
The new enlarged photo will be 16 in by 30 in
Step-by-step explanation:
We are given that the dimensions of the original photo are 4 in and 7.5 in
The photo will be enlarged by 400% of its original size
This means that:
new dimension = 400% * old dimension
Applying this to the given dimensions:
New length = 400% * 4
New length = 4 * 4 = 16 in
New width = 400% * 7.5
New width = 4 * 7.5 = 30 in
Hope this helps :)
