To find the dimensions of Jan's enlargement using a scale factor of 3.5, you would multiply the original dimensions by 3.5.
For example, if the original dimensions are:
- Width: \( W \)
- Height: \( H \)
The enlarged dimensions would be:
- Enlarged Width: \( 3.5 \times W \)
- Enlarged Height: \( 3.5 \times H \)
If you provide specific original dimensions, I can calculate the exact enlarged dimensions for you. Otherwise, the general method is to multiply each dimension of the original sketch by 3.5 to obtain the enlarged dimensions.
