Exploring Area of Composite Figures

The video tutorial explains how to calculate the area of a composite figure consisting of a square, a trapezoid, and a triangle. It begins by identifying the given measurements and unknowns, then uses the Pythagorean theorem to find the missing side of a right triangle. The dimensions of the square and trapezoid are calculated next. Finally, the areas of each shape are computed and summed to find the total area of the composite figure.

What shapes make up the composite figure discussed?

• Circle, Triangle, Hexagon

• Square, Trapezoid, Triangle

• Square, Circle, Triangle

• Rectangle, Trapezoid, Circle
