Java

Create a Triangle class with attribute sides a$,$b$,$c and methods calculateArea$()$ and calculatePerimeter$()$

Create a RightAngleTriangle class inheriting Triangle with overridden methods calculateArea$()$ and calculatePerimeter$()$

in the methods do the relevant calculations and return the result.

Write a App called TriangleApp that would instantiate Triangle object with sides and RightAngleTriangle with side.

Write a separate method called calculateAndPrint$()$ with a formal parameter of type Triangle. call calculateArea and calculatePerimeter methods inside and print the results.

In the main method of the App call the calculateAndPrint$()$ method for both Triangle object and RightAngleTriangle object

Area of RightAngleTriangle : $1/2*$ base $*$ height

Area of Triangle$($In general$)$: $$s$($s $-$ a$)($s $-$ b$)($s $-$ c$)$

s $=($a $+$ b $+$ c$)/2$
