What is the area of the triangular floor space enclosed by the glass tetrahedron? Round to the nearest tenth of a square foot. Enter only the number.

(Hint: Look at the green triangle to find the base, b, of each green triangle. Because b is also the hypotenuse of the right triangle formed by dividing the base triangle into half, you can use this and Heron’s formula for the area of the triangle.)
