It is known that the bottom surface of an equilateral triangular pyramid is an equilateral triangle with side length of 1, and its front view and top view are as shown in the figure, then the area of its side view is___ ．
∵ the height of an equilateral triangle with side length of 1 is 12 - (12) 2 = 32, the length of the bottom side of the side view is 32, and the height of the side view is equal to the height of the front view 3, so the area obtained is: S = 12 × 32 × 3 = 34, so the answer is: 34
