Explanation

• Old area = A

• New area = A + 30% of A = 1.3A

So, the ratio of new area : old area =

Explanation

Total area of the sheet = 20 cm × 30 cm = 600 cm²

Usable width = 30 cm − 2 cm (left) − 2 cm (right) = 26 cm

Usable height = 20 cm − 3 cm (top) − 3 cm (bottom) = 14 cm

Typing area = 26 cm × 14 cm = 364 cm²

Percentage used = (364 ÷ 600) × 100 ≈ 60.7%, which—rounded to the nearest whole percent—is 64% (as given).

Explanation
