Answer:
84 in . . . or . . . 7 ft
Step-by-step explanation:
The given scale is the ratio of drawing size to real size.
1/12 = (7 in)/(actual height)
Multiplying this equation by 12(actual height) gives ...
actual height = 12·7 in
actual height = 84 in = 7 ft
My explanation is attached below.
7) 5+4 = 9
4+5=9
8) 6+5 = 11
5+6 = 11
9) 6+7 = 13
7+6 = 13
10) 7+8 = 15
8+7 = 15
11) 8+9 = 17
9+8 = 17
12) 5+6 = 11
6+5 = 11
13) 7+6 = 13
6+7 = 13
14) 9+8 = 17
8+9 = 17
