Answer 1

77

Explanation:

Answer 2

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

the answer is
77 m
