Question

45. A blueprint for a house has a scale of 1:55. A wall in the blueprint is 6 in. What is the length of

the actual wall?
330 ft.
110 ft.
27.5 in.
027.5 ft.

Answer 1

the correct answer is 27.5 feet

Explanation:

The scale of a blueprint is a ratio that represents the relationship between the size of an object on the blueprint and the size of the actual object. In this case, the scale is 1:55, which means that for every 1 unit of length on the blueprint, the actual object is 55 units long.

If a wall on the blueprint is 6 inches long, then the actual wall is 55 times longer, or 6 inches * 55 = 330 inches. Since there are 12 inches in a foot, the actual wall is 330 inches / 12 inches/foot = 27.5 feet long. Therefore, the correct answer is 27.5 feet
