AREA OF COMPOSITE SHAPE ACTIVITY
Maths Challenge Activity- to keep your students engaged, thinking critically and making connections to 2D shapes.
This activity requires students to determine the area of a shape based on the given dimensions. It also encourages them to think creatively and come up with mathematical strategies to solve unknown lengths.
The aim of this activity is to:
– Increase their fluency and confidence in geometry and measurements
– Develop understanding of a variety of 2D shapes in real life problems.
In this activity, students will practice finding the area of a composite (irregular) figure involving a rectangle, a triangle and semi-circles.
Step-by-step solutions are also included.
Learning Outcomes:
- Establish the formulas for the areas of rectangles, triangles and
- parallelograms, and use them in problem-solving.
- Solve problems involving the area of circles.
- Calculate the area of the composite shape.
Comply with Australian Curriculum:
Calculate areas of composite shapes (ACMMG216)
