To find the actual width of the bedroom, we need to use the scale ratio provided in the blueprint: 0.50in = 1ft.
Given that the bedroom on the blueprint is shown as 5.5 inches wide, we can calculate the actual width by multiplying the width on the blueprint by the scale ratio.
Actual width = Width on blueprint * Scale ratio
Actual width = 5.5 inches * 1ft / 0.50 inches
Simplifying the units, we have:
Actual width = 5.5 / 0.50 ft
Actual width = 11 ft
Therefore, the actual width of the bedroom is 11 ft.
The correct answer is A) 11.
To find the actual width of the bedroom, we need to convert the width on the blueprint to real-world dimensions using the given scale.
First, we know that on the blueprint, the width of the bedroom is given as 5.5 inches. According to the scale provided (0.50in = 1ft), every 0.50 inches on the blueprint represents 1 foot in reality.
So, we can set up a proportion to solve for the actual width of the bedroom:
0.50 inches / 1 foot = 5.5 inches / x feet
Cross-multiplying, we get:
0.50 inches * x feet = 5.5 inches * 1 foot
Simplifying further:
0.50x = 5.5
Dividing both sides of the equation by 0.50, we have:
x = 5.5 / 0.50
x = 11
Therefore, the actual width of the bedroom is 11 feet.
So the correct answer is A) 11.
