All dimension is multiplied by 4.

Area of the figure will be multiplied by = ?

We know that,

`Area\ \alpha \ (Length)^2`

If length is multiplied by 4.

`Area\ \alpha \ 4^2 (L)^2`

Where L is the dimension of the figure.

`Area\ \alpha \ 16 (L)^2`

Area of the figure will be multiplied by 16.

Hence, correct answer is option D.
