Answer / Rohit Rai
In Objective-C, you can define methods (functions) inside classes. To declare a method, use the following syntax:
```objectivec
-(returnType)methodName:(parameters);
```
Here's an example of a method that calculates the area of a rectangle with two parameters for width and height:
```objectivec
- (double)calculateRectangleAreaWithWidth:(double)width andHeight:(double)height {
double area = width * height;
return area;
}
```
To call the method, create an instance of the class containing the method and invoke it:
```objectivec
Rectangle *rectangle = [[Rectangle alloc] init];
double result = [rectangle calculateRectangleAreaWithWidth:10.0 andHeight:5.0];
NSLog(@"The area is %f", result);
```
