GRADE 7 MATHEMATICS (7.4) Patterns, relationships, and algebraic thinking. The student represents a relationship in numerical, geometric, verbal, and symbolic form. The student is expected to: (A) generate formulas involving conversions, perimeter, area, circumference, volume, and scaling. (B) graph data to demonstrate relationships in familiar concepts such as conversions, perimeter, area, circumference, volume, and scaling
1 inch to represent 3 feet in a scale drawing of a new library. 2 One room of the library where microfilm will be stored is 15 feet by 18 feet. Another room where videos are stored is 12 feet by 24 feet. What will be the dimensions of these two rooms on the blue print? Show your work.
A blueprint uses a scale of
Microfilm room:
Video room: The entire library will be 120 feet by 150 feet. What are the dimensions on the blue print of the library? What is the scale factor used for the scale drawing? Remember the dimensions need to be in the same unit to find the scale factor.
