The width of the rectangle is given by ...
W = A/L
W = (20 cm²)/(8 cm) = 2.5 cm
__
The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...
W = (24 cm²)/(10 cm) = 2.4 cm
The percentage change in size is ...
((2.4 cm)/(2.5 cm) -1) × 100% = -4%
The width of the rectangle decreased less than 5%. Noah is correct.
