The length of a pyramid is one of the sides of the base, typically the longer one.
(If you meant it literally, then the length of "A PYRAMID" is 9.)

A pyramid has 5(five) faces. Made up of 4 trigular faces and a square base . You need to know the length of the square base and the length of a sloping face , from the top of the pyramid to the centre of the base line. Hence Area of triangl;e = 0.5 X sloping length X base) Area of the four triangles = 4 X 0.5 X sloping length X base) Area of base = length X length . = length^(2) Hence the area of the pyramids faces = 4 X 0.5 X sloping length X base + length^(2) NB Notice this last term is 'added' , not multiplied.
