Final answer:
To find the actual length of the house, we need to use the scale ratio of the floor plan. In this case, the scale is 1/4 inch equals 4 feet. Using a proportion, we can find that the length of the house is 13.5 feet.
Step-by-step explanation:
To find the actual length of the house, we need to use the scale ratio of the floor plan. In this case, the scale is 1/4 inch equals 4 feet.
So, if the house measures 3 and three-eighths inches on the floor plan, we can set up a proportion to find the actual length:
1/4 inch / 4 feet = 3 and 3/8 inches / x feet
Cross multiplying, we get 1/4 * x = 4 * (27/8)
Simplifying, we find that x = 108/8 = 13.5 feet.
Therefore, the length of the house is 13.5 feet.
