Calculate the colored area with the given dimensions.
THINGS TO TRY
The shaded area consists of three pieces:
The first piece is the colored area between two equilateral triangles, with thickness
; the length of the side of the outer triangle is
The second piece is a parallelogram with width equal to
and height equal to
The third piece is a rectangle with width equal to
and height equal to
. It has the same area as the parallelogram.
