$AB=AC$ is an isosceles triangle

From vertex $B$ transfer height to side $AC$ and vertex $A$

Lower an altitude to the base $BC$ so that the altitudes meet at point $F.$

Given :

B

$1FE=3FH$

$1AF=5FH$

Write a program that receives two numbers from the user when:

The first number represents the length of side $AH$

The second number represents the length of side CB

Calculate the area marked in green. Finally the program will print the result to the screen as

follows: "The green area is:
