Ummm. If the 11 is the base of the triangle. And the 8 is the height. Then the equation will be
2(11)(8)+11^2. Which will equal to 297cm.
If I’m incorrect on the height and base thing. The equation for finding surface area of a pyramid is
2•(base)•(height)+(base) squared = surface area
2(11)(8)+11^2. Which will equal to 297cm.
