Complete Question
A drawing of a basement uses the same scale as the example above which is 1 inch to 10 ft. The basement is 28ft wide and 35 ft long. how wide and long is the drawing? show your work
2.8 inches wide and 3.5 inches long.
Step-by-step explanation:
Scale drawing
1 inch = 10 feet
= 1 inch/10 feet
For the Width of the basement
The basement = 28ft wide
= 1inch/ 10 feet = x inch/28ft
= Cross Multiply =
10 feet × x inch = 28feet × 1 inch
x inch = 28 feet × 1 inch/10 feet
x = 2.8 inches
The drawing = 2.8 inches wide
The length of the basement = ft long
1inch/ 10 feet = x inch/35ft
= Cross Multiply =
10 feet × x inch = 35feet × 1 inch
x inch = 35 feet × 1 inch/10 feet
x = 3.5inches
Therefore, the drawing is 2.8 inches wide and 3.5 inches long
