Step-by-step explanation:
1) you could divide the shape into a triangle and rectangle.
area of rectangle is height×width
area=9×9
=81
area of a right angled triangle is (base ×altitude) ÷2
area=(4×9) ÷2
area=18
total area=18+81
=99
2) divide again into triangle and rectangle.
rectangle=6×5
=30
triangle=(4×3) ÷2
=6
total area=6+30
=36
