To find out how many times larger the area of the enlarged rectangle is compared to the original rectangle, we can follow these steps:

1. Calculate the area of the original rectangle:

– Let the original width be ( w ) and the original length be ( l ).

– The area ( A_{original} = w times l ).

2. Dimensions of the enlarged rectangle:

– The width is doubled: new width = ( 2w ).

– The length is tripled: new length = ( 3l ).

3. Calculate the area of the enlarged rectangle:

– The area ( A_{enlarged} = (2w) times (3l) = 6wl ).

4. Compare the two areas:

– To find how many times larger the area of the enlarged rectangle is compared to the original rectangle:

[

text{Ratio} = frac{A_{enlarged}}{A_{original}} = frac{6wl}{wl} = 6.
]

Thus, the area of the enlarged rectangle is 6 times larger than the area of the original rectangle.

The answer is A. 6.
