Ответ:
If all the dimensions of the figure are multiplied by 4, the area of the figure will be multiplied by: 16
Step-by-step explanation:We know that if all the dimensions of a figure are changed by some factor i.e. all the dimensions are multiplied by the same number then the area of the figure is multiplied by the square of that number.
Here all the dimensions of the figure are multiplied by 4.
This means that the area of the figure is obtained by multiplying the previous area by 4²=16
Hence, the new area of figure will be: 13×16=208 square inches.
The correct option is: Option: D
