You use a block square
The height is a leg of a right triangle. The other leg is 1/2 of the side of the original triangle and the hypotenuse is a side of this same triangle. Use the Pythagorean theorem to solve for the height: If s is the length of the sides of the equilateral triangle, The height is the square root of s squared minus (s/2) squared. Since (s/2) squared is s squared over 4, s squared minus (s/2) squared is 3/4 s squared. I'll let you finish it off.

You can't get a curved shape on minecraft. Everything is squared.
A = S squared is the formula for area of a square A = area S = lenght of side
Squared and triangles
Well, you know that in order to classify a shape as a rectangle all of the sides have to be congruent or 90 degrees. If you draw the diagonal of that rectangle, you come up with two right triangles. So you can use the Pythagorean theorem (a squared+b squared=c squared) to find out the diagonal. Ex: If the length=4, and width=3, then diagonal=5, because 4 squared+3 squared=5 squared.
s squared or s*s
A centimetre squared is a measure of area; it can have any shape. The easiest area of 1 centimetre squared (to draw/visualise) is a square with one centimetre on each side.
you use A squared plus B squared equals C squared
s times s times s times s
Velocity squared is calculated by multiplying the velocity of an object by itself. For example, if the velocity of an object is 10 m/s, then the velocity squared would be 10 m/s * 10 m/s = 100 m/s^2.
