So , the area of the bedroom =
[which is an exponential expression]
Simplify it
The area of the bedroom = 
Also, the carpet she needed = Area of the bedroom.
Thus , She needed 144 square feet of carpet.
28a⁴b: 2 · 2 · 7 · a · a · a · a · b
16ab: 2 · 2 · 2 · 2 · a · b
GCF(28a⁴b, 16ab) = 4ab
The answer is A.
