Can you describe what a compound shape is? Compound Shapes Can you describe what a compound shape is? Shapes Compound shapes

Recap: How do you work out the area of... Area of rectangle = Base x height Area of triangle = (base x perpendicular height) ÷ 2

Compound Shapes A compound shape is one that is made up of other shapes. To find the area of a compound shape, you need to split it up into shapes you know: Label each section. Write down all dimensions. Find the areas. A: B: A + B = __________ 7cm 13cm 6cm Remember, there is often more than one way to split up a shape! 4cm

Compound Shapes Label each section. Write down all dimensions. 4cm Label each section. Write down all dimensions. Find the areas. A: B: A + B = __________ 4cm 7cm 6cm

Compound Shapes Label each section. Write down all dimensions. Find the areas. A: B: A + B = __________ 8cm 13cm 15cm

Compound Shapes Label each section. Write down all dimensions. Find the areas. A: B: C: A + B + C = __________ 4cm 22cm 15cm 18cm 25cm

Compound Shapes Label each section. Write down all dimensions. 15cm Label each section. Write down all dimensions. Find the areas. A: B: C: A + B + C = __________ 14cm 8cm 20cm 9cm 18cm
