Answer:
16.5 Squared Inches
Explanation:
A 8.5''x11'' paper would be 7.5 in by 10 in with 1 inch margins. 7.5 x 10=75 in^2.
A landscape paper is 11''x8.5'' which would be 9 in by 6.5 in with 2 inch margins. 9 x 6.5=58.5 in^2.
75 inches squared-58.5 inches squared is 16.5 inches squared.
Therefore, you would lose 16.5 squared inches of writing space.
