Answer:
27.71 square units
Step-by-step explanation:
The shaded region is a triangle;
Area of a triangle = 1/s * base * height
base = 16/2 = 8
To get the height, you will use the pythagoras theorem
h^2 = 8^2 - 4^2
h^2 = 64 - 16
h^2 = 48
h = 6.93
Area of the shaded region = 1/2 * 8 * 6.93
Area of the shaded region = 4 * 6.93
Area of the shaded region = 27.71 square units
