Answer:
Step-by-step explanation:
Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon.
Calculate the perimeter. The perimeter is the combined length of the outline of any two-dimensional figure. For a regular polygon, it can be calculated by multiplying the length of one side by the number of sides (n).
Determine the apothem. The apothem of a regular polygon is the shortest distance from the center point to one of the sides, creating a right angle. This is a little trickier to calculate than the perimeter.
The formula for calculating the length of the apothem is this: the length of the side (s) divided by 2 times the tangent (tan) of 180 degrees divided by the number of sides (n).

I graphed the function and found answer.
Answer:
(b) 600 − x
Step-by-step explanation:
(a) R = 600x − x²
R = x (600 − x)
(b) Revenue is quantity times price:
R = xP
Substituting from part (a):
x (600 − x) = xP
600 − x = P
