As shown in the figure, the side edge length of a straight triangular pyramid is 2, the bottom is an equilateral triangle with side length of 2, and the front view is a square with side length of 2. Calculate the area of its left view Very anxious! Why is the width the height on the side of the bottom regular triangle

Straight triangular prism, right?
The left view is a rectangle with the same height, that is, the length of the side edge is equal to 2,
The width is the height on the bottom edge of the bottom regular triangle, which is √ 3,
Therefore, the left view area s = 2 * √ 3 = 2 √ 3
