Answer:

Area and Perimeter Formulas of a Right Triangle

Any triangle with one of the angles equal to 90° is called a right angled triangle or simply a right triangle.  

The area A of a right triangle with sides a and b is given by  

A = (1 / 2) a × b  

The perimeter P of a right triangle with sides a and b and hypotenuse h is given by  

P = a + b + h  

Using the  

Pythagorean theorem, we can write  

h 2 = a 2 + b 2

which gives  

h = √(a 2 + b 2)  

Hence the perimeter can be written in terms of a and b only as follows:  

P = a + b + √(a 2 + b 2)
