directrix · Answer

Lemme check the formula.

directrix · Answer

Okay.

Area of Square Pyramid = 2 * e * L + e^2 where e is the length of the base edge, L is the slant height, and e^2 is the area of the base of the pyramid.

so ..

Trouble:  Is this posted correctly: square pyramid with length 9 ft.
I don't know what the length of a pyramid means. Would you check your problem source?

It's fine Directrix. (:

directrix · Answer

I am going to assume that 9 is the base edge length. (The question is poorly worded)
Let's see what pops out.

directrix · Answer

Total Area = 2*9*12 + 9^2

@dopegyal_   -->   2*9*12 + 9^2 = ?
