So it's going to be square root of 3s squared over 2 times 2 over 4. So this is the area of an equilateral triangle as the function of the length of its sides. So what's the area of this business going to be? So the area of our little equilateral triangle, let me write combined area. Let me do that in a neutral color. So let me do that in white. So the combined area, I'll write it a sub c, is going to be equal to the area of my triangle, a sub t, plus the area of my square.
