Given:

The original dimensions of a poster are 6 inches  by 7 inches.

It is enlarged by a factor of 2.

To find:

The dimensions of enlarged poster.

Solution:

Let the length of the original poster is 6 inches and width is 7 inches.

It is enlarged by a factor of 2. It means, we have to multiply each dimension by 2.

Length of enlarged poster = 2 × 6 inches

                                            = 12 inches

Width of enlarged poster = 2 × 7 inches

                                          = 14 inches

Therefore, the dimensions of enlarged poster are 12 inches by 14 inches.
