An architect notices that the scale on a blueprint he is using has been torn off. However, he sees that a 21.6-foot wall that has been built is 6 inches long on the blueprint. What is the scale for this blueprint?

A1 in. : 3.6 ft.
B1 in. : 6.3 ft.
C1 in. : 36 ft.
D1 in. : 63 ft.

6 / 21.6 = 1 / x
cross multiply
6x = 21.6
x = 21.6/6
x = 3.6

so ur answer is A : 1 in : 3.6 ft

Answer:

A. 1 in. : 3.6 ft.

Step-by-step explanation:

In order to get the scale on the blueprint we just have to divide the measure in real time by the number of the blueprint, if whe know that there´s a wall that is 21.6 feet long, and in the blue print is 6 inches long we just divide it:

\(Scale:\frac{21.6}{6}\)

\(Scale:3.6\)

So now we know that for every inche in the blueprint there has to be 3.6 feet on the real construction.
