Enlarging by 250 % means that the scale factor is 2.5.
15 in. by 22.5 in.
Practice makes perfect
We are given that Jamie wants to use a photocopier to enlarge her design, and she sets the copier to 250 %. This means that the enlarged design is 2.5 times larger than the original one. Therefore, we should multiply each of the original dimensions by 2.5.
Original dimensions:& 6in. by9in.
Enlarged dimensions:& 6( 2.5)in. by9( 2.5)in.
Finally, let's evaluate these products.
Enlarged dimensions:& 15in. by22.5in.
