the complete question in the attached figure

we know that
[scale]=1 in / 30 ft
scale=[measure in the drawing]/[measure in the actual]
[measure in the actual]=[measure in the drawing]/[scale]
so
[measure in the drawing]=1.25 in
scale=1/30

then
[measure in the actual]=[1.25]/[1/30]------> 1.25*30-----> 37.5 ft

the answer is
the Actual height is 37.5 ft
