Question

In this assignment I must find the area of the shapes I know how to do this, I just need a little help on the trapezoid and the circular part of the picture (The shapes highlighted in PINK is what I need help with) I don't know how to use the area formula for those two shapes

Answer 1

trapezium area = (1/2(a+ b))xh where a and b are the two parallel lengths and h is the height.
semi cirlce area= (pi x r'2)/ 2
