Answer:
356.93sq. cm
Explanation:
Area of the composite figure = Area of rectangle + Area of semicircle
Area of rectangle = length * wiidth
Area of rectangle = 14cm * 20cm
Area of rectangle = 280 sq. cm
Area of semicircle = πr²/2
Area of semicircle = 3.14(7²)/2
Area of semicircle = 3.14 * 49/2
Area of semicircle = 76.93 sq. cm
Hence the area of the figure = 280 + 76.93
Hence the area of the figure = 356.93sq. cm
