Answer:

Step-by-step explanation:

Circle - A = πr²

Semi circle - A= 1/2 πr²

Answer:

(see below)

Step-by-step explanation:

A) Trapezoid

    3. A = 1/2 (base 1 + base 2 ) x height

~

B) Circle

    1. A = πr²

~

C) Rectangle

    5. A = length x width

~

D) Semicircle

    4. A = 1/2 πr²

This is half of a circle, so it would be 1/2 of the area of a circle, hence the 1/2.

E) Triangle

    2. A = 1/2 base x height

If you cut a rectangle in half diagonally, you have two triangles. So it's half the area of a rectangle. This is one way to think about it, hence the 1/2.
