as you can see, each face of the pyramid is an equilateral triangle. The area of an equilateral triangle is http://www.mathwords.com/a/area_equilateral_triangle.htm \[ \text{Area of one face }= \frac{s^2 \sqrt{3}}{4} \] replace s with 4, and do the arithmetic. The pyramid has 3 faces, so multiply that area by 3 to get the lateral area of your pyramid
