We know that with scale factor 1=1 in/4 m <span>the longer side of the ballroom-------> 44 m scale factor= measure model/measure actual measure model=scale factor*measure actual </span>measure model=(1/4)*44------> 11 in
with scale factor 2=1 in/7 m measure actual=measure model/scale factor measure actual=11/(1/7)-----> 77 m
