The area of the figure is 70.3 to the nearest 10th place.
Finding the area of a rectangle and the the area of a semicircle.
The area of the rectangle is the multiplication of the length of the rectangle by the width of the rectangle. In the given diagram, the length = 16, and the width = 4
Area of the rectangle = 16 × 4
Area of the rectangle = 64
The area of the semicircle refers to half of the area of the circle;
Area of semicircle =

- where; the radius = d/2 = 4/2 = 2
Area of semicircle =

Area of semicircle = 6.3
The area of the figure = area of rectangle + area of semicircle.
The area of the figure = 64 + 6.3
The area of the figure = 70.3
