Do you have a codes using C?
Fun for Area of circle:
Area of circle A = PI*r*r
Where PI = 22/7 or 3.14
Area of traingle:
Area of tri A = 1/2*base*vedh
Where vedh is a length of side which is 90 degree to base.(in case of right angle triangle)
OR
vedh is a length of line which is 90 degree to base side and passes through top meeting junction.
