For this case we have the following dimensions:
(4) * (5)
Applying a scale factor we have:
(4k) * (5k)
The value of k is given by:
k = 48/4
k = 12
Or equivalently we have:
k = 60/5
k = 12
Substituting values we have:
(4 (12)) * (5 (12))
From here, we obtain the dimensions of the wall banner:
(48) * (60)
Answer:
A. Expansion
