since each dimension is scaled, the area becomes
(15/2.5)(25/2.5)
(15/2.5)(25/2.5)
area is proportional to scale squared
volume is proportional to scale cubed

A model of a rectangular patio at a landscaping business will be enlarged by a scale factor of 2 when it is installed in a customer’s back yard. The area of the new enlarged patio will be 160 square feet. Which is the area of the landscaper’s model?
120
The answer is 120
The answer is 120 (I think)
15 x 20 = 300
30 divided by 2.5 equals 120.
15 x 20 = 300
30 divided by 2.5 equals 120.
I mean 300 divided by 2.5 equals 120
