The floor of the school has the shape of triangle.
So, the area of the floor is equal to the area of that triangle with base = 26 in, and height  = 33 in.
The area of triangle = 0.5 * base * height 
            = 0.5 * 26 * 33 = 429 in²

∴ The area of the floor = 429 in²
The floor are is 429 in².

Since the floor has a shape of triangle, we need to use the formula:
Area-1/2base x height
Given:
 base = 26 in, and height  = 33 in.

SOlution:The area of triangle = 0.5 * base * height             = 0.5 * 26 * 33 = 429 in²
The area of the floor = 429 in²
