If you look at the attached graphic, you will see that the altitude (or height) of an equilateral triangle is:
Height = side length * sq root (3) / 2
Area = side^2 * sq root (3) / 4
Height = side length * sq root (3) / 2
Area = side^2 * sq root (3) / 4
we have
If c is the independent variable
then
p is the dependent variable
so
clear variable p
Divide by both sides
Adds both sides
Write the equation in function notation
therefore
the answer is
the equation in function notation is equal to
