Finding Area,Perimeter, of a rectangle through inheritance

Question

inheritance

Answer 1

At first think about rectangles. It has 4 sides but it should be clear that you don't need all sides. Only two: length and width.

Then search for the formulars to calculate area and perimeter.

A class has attributes (data) and methods.
length and width are your attributes. calcArea and calcPerimeter are your methods.

Which types? I think double is good.
double length
double width
calcArea -> return a double value for the area
calcPerimeter -> return a double value for perimeter

I am not sure why you should need inheritance. Here is a link to the lesson: https://www.sololearn.com/learn/CPlusPlus/1907/?ref=app
