The equation for this is a^2+b^2=c^2 so your equation would be 7^2+20^2=X
So you square the 7 and the 20 then take the square root of X and you get
X=21.19

Answer:
as a semicircle, a hexagon, and a rectangle
Step-by-step explanation:
The first attachment shows the decomposition according to the answer choice above. It would make area computation about as simple as it could be.
__
The second attachment shows a decomposition with a circle. It leaves a very odd shape in the middle that is not easily divided into triangles, rectangles, or trapezoids.
The third attachment shows a semicircle, a pentagon, and two triangles. The pentagon is <em>not a regular pentagon</em>, so might require further decomposition in order to determine its area.
