I don't understand yet ;) It looks like you multiplied 9 * 4. Is that the area of a side of the shape?

Area of a triangle: = 1/2 * base * height You had the right idea of multiplying by four, though... there are four sides.

So, for the four triangle sides, your area of each side will be 1/2 * 4 * 9 1/2 * 4 * 9 = 18 And there are 4 of those triangle sides, so 4 * 18 = 72 But you still need to add the area of the square base.
