Lesson Summary

House plans are scale drawings. If you knew the scale factor for the plans, you could calculate the dimensions or area of any part of the house by first taking measurements from the plans themselves. Any modifications to a scaled plan must be drawn to the same scale.
In this lesson you explored scale factors and their relationship to the perimeter and area of squares and rectangles, similar to the square and rectangles illustrated on the technical diagram.
In this lesson you explored these questions:
- How does changing one or more dimensions of a rectangle affect the rectangle’s perimeter?
- How does changing one or more dimensions of a rectangle affect the rectangle’s area?
