if we make that more general; LA = base perimeter * height if height is increase by 1 LA = B(h+1) > LA = Bh + B

the perimeter of the base  LA = p*h where p is the perimeter of the base If h' = h + 1, then the lateral area of the taller prism is LA = p*(h+1) = ph + p. Comparing ph to ph + p shows that the lateral area of the taller prism is increased by the perimeter of the base.
