Answer:1.2
Step-by-step explanation:
Given
Original length of square is 6
Also scaled copy has side length of 5
So using unitary method to find the correct scaling
6 unit of square is equivalent to 5 units of scaled copy
Thus 1 unit of copy is equivalent to 1.2 units of square length
So in final answer we need to multiply by a factor of 1.2 to get the original square length dimensions.
