Write a Fortran program to compute the area of a triangle determined by jointing the three points (x1,y1), (x2,y2) and (x3,y3) given by a user who executes the program. Use implicit none statement in your program. Write a Fortran program to compute the logarithm of a number to an arbitrary base b, i.e., log,x, using the intrinsic function ALOG10 (x). Test the program by calculating the logarithm to the base e of number x using ALOG(x) Use implicit none statement in your program
