Now we can take the principal root of both sides, and we get h is equal to the square root of 3 times s over 2. So now we can just substitute back right over here, and we get our area is equal to 1 half s times h. Well, h is this business, so it's s times this. So it's 1 half times s times the square root of 3s over 2, which is going to be equal to s times s is s squared. 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.
