Compound shapes? • Are shapes made of more than one shape • To calculate area • Break it up into separate shapes • Calculate each area • Add them
A Triangle B Rectangle 1m For example 10 x 1 2 = 5 m2 A 10 x 6 = 60 m2 7m 6m B TOTAL = 65 m2 10m
A Trapezium B Rectangle 12m 4m For example 8m 3m (7 + 12) x 4 2 = 38 m2 B 15 x 8 = 120 m2 15m A 7m TOTAL = 158 m2 12m
