Answer:

1 inch on blueprint = 66 inch of real height

Step-by-step explanation:

Actual height of the wall is given as

H=38.5 ft.

so if we convert it into inch then we have

H=38.5 x 12

H=462inch  

now we know that this is shown by height of 7 inch in blueprint

so we have

7 inch on blueprint = 462 inch real height

so 1 inch of blueprint will show

h=\frac{462}{7} =66inch

so here we can say that scale will be

1 inch on blueprint = 66 inch of real height
