Answer 1

13.5 feets

1 inch

Explanation:

Given :

Blueprint length (in.) __2 4 6 8 10 12

Actual length (ft) _____3 6 9 12 15 18

From the data:

Blueprint : actual

2 in : 3 feets

Length of wall on blueprint = 9 inches

Actual length of wall :

2 inches = 3feets

9 inches = x

Cross multiply

2x = 27

x = 27 /2

x = 13.5 feets

B.)

For actual width = 1.5 feets

2 inches = 3feets

x = 1.5 feets

3x = 2 * 1.5

3x = 3

x = 3/3

x = 1 inch
