Answer:
52.5cm²
Explanation:
The shape is made up of a triangle and rectangle. To find the total area, find the area of the triangle and the area of the rectangle, and add them together:
Area of triangle = (1/2)(base)(perpendicular height)
=(1/2)(8-1-2)(5)
=(1/2)(5)(5)
=12.5cm²
Area of rectangle = (length)(width)
=(8)(5)
=40cm²
Total area = 12.5+40 = 52.5cm²
