Question

The plan of a terrace has a scale of 2 inches : 6 feet. What is the actual length if the scaled length of the terrace is 54 inches?

Answer 1

x = 162 ft

Explanation:

Let's take the scaled length and plug it into our scale to find the actual length.

2 inches : 6 feet = 54 inches : x feet

`(2 in)/(6 ft) = (54 in)/(x ft)`

Cross-multiply.

2x = 54 * 6

2x = 324

x = 162 ft

Answer 2

4.5 is the correct answer
