A triangle with side 8 and height 10 cannot be equilateral if the side and height are measured in the same units (inches, cm, miles etc). And if they are not, there is not sufficient information to answer the question.

Using Pythagoras' theorem the height of the equilateral triangle works out as about 7 cm and so with the given dimensions it would appear to be quite difficult to work out the lateral area.

It is the perimeter of a triangle times the length of the prism (in square units).
It is: 0.5*base*perpendicular height
You find the height by using Pythagoras' theorem and then 0.5*base*height = area.

only solids have "lateral area". triangles have "area". the area of a scalene triangle is given by heron's formula. height not needed.
It is the perimeter of a triangle times the length of the prism (in square units).
An equilateral triangle with a height of 20 has a base of 23.1 (23.09401), not 15. If the base is 15 then the height will be 13 (12.99038).
It is: 0.5*base*perpendicular height
Area = 1/2*base*perpendicular height.
Its area is 46.8 (46.76533) square inches.

The height of an equilateral triangle is √3/2 x side_length. So for an equilateral triangle of side length 2a, the area is: area = 1/2 x base x height 1/2 x (2a) x (√3/2 x 2a) = √3 a2
