**Reiny**, Monday, May 21, 2012 at 1:45pmI will assume that by "lateral area" you mean the surface area without the two triangular bases

So if the side of the equilateral triangle is s and the height is h, then the area of the three rectangles is 3sh

new height is (h+1)

so new area = 3s(h+1)

= 3sh + 3s

so the increase is 3s, which is the "perimeter of the base"
