To find the length of the room on the blueprint, we first need to convert the actual length of 28 feet to the equivalent length on the blueprint.
1/2 inch represents 4 feet on the blueprint, so we need to set up a proportion to find the length on the blueprint:
(1/2 inch) / (4 feet) = (x inches) / (28 feet)
Cross multiplying, we get:
4x = 28 * 1/2
4x = 14
x = 3 1/2
Therefore, the length of the room on the blueprint is 3 1/2 inches.
The answer is C. 3 1/2 in.
In the scale used on a blueprint, 1/2 inch represents 4 feet.
