Right angled triangle

The circumference of a right angled triangle is the sum of the three side lengths:

Circumference=a+b+c

The area is given by the area formula for an arbitrary triangle:

Area=frac{1}{2}*B*h

If the triangle is right angled, as in this case, the side a is the same as the height an b is the same as the base line.

Area=frac{1}{2}*b*a
