Simply, if you know the height of the triangle, that is the length from an angle to an opposite base, a line that is an altitude of the triangle, then you could find the area using the simple formula for area of any triangle, which is 0.5(base*height) * being multiply of course.

That bottom line labeled 'b' is base and that altitude labeled 'h' is height.
If the height is not readily available, then the alternative formula just for equilateral triangles is (assuming that s is the length of one side)
[s2*squareroot(3)]/4
or in English
parentheses side squared times the square root of 3, end parentheses over 4.

How do you find the lateral area of a triangle prism?
You can't.
How do you find the area of a regular pentagon?
It can be divided into 5 equal triangles so find the area of a triangle and then times it by 5. Area of a triangle is 0.5 times base times perpendicular height.
How do you find lateral surface area of cube?
If a is the side,lateral surface area of cube=4a2
Where would you find yellow triangle squares on lateral markers?

How do you find the slant height of a cone if you have surface lateral and radius?
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
