Question

O solutions submitted (max: Unlimited) A fenced enclosure consists of a rectangle of length Labutted to a semicircle of radius R. see figure above. The enclosure is to be built to have an area A of 1800 / The cost of the fence is $45/t for the curved section and $35/t for the straight sides. You are asked to 1. Create the length vector from 0 to 100 with increment of 5. 2. Compute the radii R for given area 3. Compute the cost (use variable cost). 4. Write a script to generate a plot of cost vs. L (L is on the x-axis and cost is on the y-axis). Dont forget to add x label, y label and title Hint: If you don't know where to start with pick a number for longth, and try to solve this problem on paper. Programming will follow the same logic and steps

L=0:5:100;
R=[];
R=(-(2*L)+sqrt((2*L).^2-4*pi/2*(-180)))/(2*pi);
cost=(2*R+2*L)*35+pi*R*45
plot(L,cost);
xlabel('X-values');
ylabel('Y-values');
title('Plot of cost vs L');
