Answer

Honshu has a greater area by 4228 square miles.

Work Step by Step

$1~mi^2 \approx 2.6~km^2$ Victoria Island has an area of $217,300~km^2$. We can convert this area to units of square miles. $217,300~km^2 = \frac{217,300~km^2}{1}\times \frac{1~mi^2}{2.6~km^2} = 83,577~mi^2$ Victoria Island has an area of $83,577~mi^2$ Honshu has an area of $87,805~mi^2$ We can find the difference in land area. $87,805~mi^2-83,577~mi^2 = 4228~mi^2$ Honshu has a greater area by 4228 square miles.
