Area is One of the following: Area = base ● height Area = ½ ● base ● height

19 What number is the Base? What number is the Height? Area Formula?

20 Area is One of the following:
Base = 16 ft. Height = 10 ft. Area is One of the following: Area = base ● height Area = ½ ● base ● height

21 Name this figure. 3.5 cm 1 cm 11 cm

22 Trapezoid 11 cm 3.5 cm 1 cm Area of Trapezoid = ½ (B1 + B2) x height

23 Decompose the Trapezoid
3.5 cm 1 cm 11 cm Area of Rectangle = 11 cm x 3.5 cm Area of Triangle1+ 2 = ½ x 3.5cm x 1cm x 2 38.5 cm cm2 = 42 cm2
