Introduction to Using Properties of Rectangles, Triangles, and Trapezoids

This summer, you decide to grow veggies to add to your garden. However, you first need to build raised garden beds in your backyard. These garden beds are in different shapes and sizes, including rectangles, triangles, and trapezoids. To build these garden beds, you will need to understand measurement, in linear, square, and cubic metrics. You will also learn about the properties of rectangles, triangles, and trapezoids to make the best garden beds possible.


Learning Outcomes

By the end of this section, you will be able to:

  • Understand linear, square, and cubic measure
  • Use properties of rectangles
  • Use properties of triangles
  • Use properties of trapezoids


readiness quiz

Before you get started, take this readiness quiz.

  1. The length of a rectangle is [latex]3[/latex] less than the width. Let [latex]w[/latex] represent the width. Write an expression for the length of the rectangle.If you missed this problem, review [link].
  2. Simplify: [latex]\frac{1}{2}\left(6h\right)[/latex].If you missed this problem, review [link].
  3. Simplify: [latex]\frac{5}{2}\left(10.3 - 7.9\right)[/latex].If you missed this problem, review [link].



In this section, we’ll continue working with geometry applications. We will add some more properties of triangles, and we’ll learn about the properties of rectangles and trapezoids.
