Transcribed Image Text:Solution Please fill in the gaps in the solution below. @startuml package Shape <|-- } { <|-- Square Shape { class { } class Rectangle { } } @enduml width
The diagram should have a package named Math that
includes a class shape which has two subclasses named
Rectangle and Square.
⚫ The Shape class has one public method named area())
which returns a float
⚫ The Square class has one private member variable of
type float named side
⚫ The Rectangle class has two private member variables of
type float named width and height.
Insert the commands that reflect your solution below.
Note: Use the member variable format <access-level> <data-
type> <identifier>, e.g. - boolean isSunny and the method
format <access-level> <return-type> <method-name>(parameter(s)))
e.g. + void execute())
