What is the area of a 16 sided regular polygon with sides of length L ?

3 Answers

Area of a regular polygon A = 1/4 *n*l^2*cot(pi/n) Where n is the number of sides = 16, l is the length of a side = L Therefore A = 1/4*16*L^2 * cot(pi/16) = 20.10*L^2. Less

area = L^2/tan(2*pi/32) ~= 5*L^2

area = 16*(L^2/tan(2*pi/32)/2) ~= 40*L^2

Suppose you have a M x N mesh grid, how many rectangulars could you draw? Could you write a code to find the prime numbers from 1 to N?

2 Answers

Just for the first one, if M and N represents the size, my answer would be (M+1)*M*(N+1)*N/4 Less

Additional information for the first one: There are N by 1 grid, there are N 1 by 1 rectangles, (N-1) 2 by 1 rectangles, ..., 1 N by 1 rectangles. Total # = N(N+1)/2. For N by M grid, total # = N(N+1)/2 * M(M+1)/2. Less
