The first one is 2x-3y/2
The second one is 1/x+2
The third one is (2x-5y)/(2x+5y)
The fourth one is x^2/z^2
First, divide the shape into two figures ( a semicircle and a rectangle)
Then, find the are or the two shapes using the area formula for a semicircle (
) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer
Associative Property of Addition hope this helps
