The scale model of a rectangular patio will be enlarged by a scale factor of 2.5 to create the actual patio. The actual patio will be 15 feet by 20 feet. Which is the area of the scale model?
48 square feet
60 square feet
120 square feet
300 square feet
120
The answer is 120
The answer is 120 (I think)
15 x 20 = 300
30 divided by 2.5 equals 120.
I mean 300 divided by 2.5 equals 120
120

(15 * 20)/2.5 = ?
since each dimension is scaled, the area becomes
(15/2.5)(25/2.5)
area is proportional to scale squared
volume is proportional to scale cubed
