Area of a Complex Figure, Area of a Trapezoid
Area of a Complex Figure, Area of a Trapezoid is a key Grade 7 math skill in Saxon Math, Course 2. To find the area of a trapezoid, we use the average of its parallel bases and its height. The textbook provides two equivalent formulas for this. Area of a Trapezoid What’s next Ne Finding the area of a trapezoid is easier than it looks.
Key Concepts
New Concept To find the area of a trapezoid, we use the average of its parallel bases and its height. The textbook provides two equivalent formulas for this.
Area of a Trapezoid $$ ext{Area} = ext{average of the bases} \times ext{height} $$ $$ A = \frac{1}{2}(b 1 + b 2)h $$ What’s next Next, you'll apply these formulas in worked examples involving both trapezoids and more complex figures. We will also practice estimation strategies for quick calculations.
