A trapezoid has an upper base of 8 cm and a lower base of 14 cm. There is a semicircle in the middle with a diameter of 8 cm. The rest are shadows. Calculate the area of shadows

Height of trapezoid = radius of semicircle = 4cm
Shadow area = trapezoidal area semicircle area
=(1/2)*(8+14)*4-3.14*16*(1/2)
=18.88 square centimeter
