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

X= 49; x = 4step 1: foilstep 2: equal both to 0step 3: find x individually
