A house blueprint shows the bedroom is 5 inches wide and the actual length of the bedroom is 20 feet wide. If the bedroom has a length of 16 feet what is the length on the blueprint?
We can use proportions to solve this problem.
Let x be the length on the blueprint. Then we have:
5 inches / x = 20 feet / 16 feet
Simplifying the right side gives:
5 inches / x = 5/4
Cross-multiplying gives:
5x = 20
Dividing by 5 gives:
x = 4
Therefore, the length on the blueprint is 4 inches.
