I want to generate the random numbers in the closed rectangular area as shown below
after generating these I have to calculate the definite integral for the function line marked by red shaded area by the Monte Carlo method. Any tips regarding this

If you mean in the range (0,4) and (0,25) -
%N = number of points you want, you can also run a for loop (upto you how you want to do)
r=rand(1,N); %generates a 1xN row of random numbers between 0 and 1
%you can also call rand twice for each number
r1=4*r; %0 to 4
r2=25*r; %0 to 25

r = rand(N,2);
rand_ab = r(:,1) * (b-a) + a;
rand_cd = r(:,2) * (d-c) + c;
rand_coords = [rand_ab, rand_cd];
