You should try this on your own using variables.
Assumed given area: pi%2Ar%5E2

Scaled down area, using linear %281%2F2%29: pi%2A%28r%2F2%29%5E2

How does the second area compare to the given original area?
Given Original, pi%2Ar%5E2.
Scaled Down by Half, pi%2Ar%5E2%2A%281%2F4%29
The scaled-down-by-half area is one quarter of the original.
