Hi can somebody please help me see if my answer to the following question is correct

Calculate the area for each of the polygons below. If you do not know an equation to use, divide the polygon into other shapes to determine the area.

I choose A because

((1² * 3 / 4 tan ))* (180/3) = 0.43301270189

1. An equilateral triangle with a side of 1 inch

A 0.43 sq in

B0.56 sq in

C0.89 sq in
