Answer:
To work this question out you need to split the shape from a complex shape to a simple shapes and finding the areas of those shapes and adding them together to get the area of the complex shape.
Looking at the figure we can make two simple shapes, a rectangle and a triangle.
To find the area of rectangle is calculated by multiplying the length and width. In this case, length is 11 and width is 8. So 11*8 = 88 cm^2.
To find the area of a triangle is by multiplying the base by the height and dividing by 2.
So for a triangle with a base of 11 and a height of 7:
(11 * 7) / 2 = 77 / 2 = 38.5
The area of the triangle is 38.5 cm^2
Therefore the area of the figure is 88 + 38.5 = 126.5cm^2
