Step-by-step explanation:

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.

Length of rectangle is 2 inches

width of the rectangle is 3 inches

Scale factor is 7

To get the length and width of scaled copy, we multiply by 7

2 times 7 is 14 inches

3 times 7 is 21 inches

So the length of scaled copy is 14 inches

width of scaled copy is 21 inches
