What is the answer to this problem Using the scale 1 in. : 4 m, Mika calculated the length, or the longer side of the ballroom, to be 44 m. She decides to change the scale to 1 in. : 7 m. What is the length of the new ballroom?
we know that with scale factor 1=1 in/4 m the longer side of the ballroom-------> 44 m scale factor= measure model/measure actual measure model=scale factor*measure actual 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
