27 subtract 72 = 45 15 subtract 45 = 30
your answer would be 30
So u just do 27*0.45 to get 12.15 and subtract that to get 14.85
m(slope)= change in y/change in x
m=-17-(-5)/3-1
m=17+5/2
m=22/2
m=11
As we can see that the sides of the rectangle have been doubled
6.2 ft changed to 12.4 ft
Now when the sides have been doubled
the Perimeter will also be doubled
So the perimeter of new rectangle should be the double the perimeter of old rectangle
So perimeter of new rectangle = 2 (16 ) = 32 feet
Option C is correct
