Answer:

The length of the wall would be  12 cm

Step-by-step explanation:

we know that

On a blueprint with a scale of 1 cm = 4 ft, the length of the wall is 9 cm

so

The actual length of the wall is equal to ------> 9*4=36 ft

If the scale of the blueprint were 1 cm = 3 ft

then

The length of the wall in the new blueprint would be  ----> 36/3=12 cm
