Question

In the scale used a blueprint , 1/4 inch represents 2 feet. On the blueprint what is the length of a room with an actual length of 20 feet?

Answer 1

On the blueprint, a room with an actual length of 20 feet will be represented as 5 inches in length.

How to find the length ?

To find the length of a room on a blueprint with an actual length of 20 feet using a scale of 1/4 inch representing 2 feet, you can set up a proportion to solve for the blueprint length:

Let x be the length on the blueprint (in inches):

(1/4 inch) / (2 feet) = x / 20 feet

1 * 20 = 4 * x

20 = 4x

Now, divide both sides by 4 to find the length on the blueprint:

x = 20 / 4

= 5 inches
