total area = lateral area + area of bases
The area of the base is the area of a triangle with perimeter of 40 inches. unless you say more about the triangle, it's not possible to determine its area.
If it's an equilateral triangle, the just figure the height by using the side which is 40/3.
Or, it may be a right triangle.
Height: 10 inches
Base Perimeter: 40 inches
Lateral Surface Area: 400 square inches (^^^this is the total surface area of the sides)
