Answer ::
- Area of rectangle = 9m² + 12m units
- Perimeter of rectangle = 12m + 12 units
Step-by-step explanation ::
Formula used ::-
- Area of rectangle = l × b
- Perimeter = 2 ( l + b )
Where,
- l = Length
- b = Breadth
To Find :-
- Area of rectangle
- Perimeter of rectangle
Solution :-
Given that,
- Length of rectangle = 3m + 6
- Breadth = 3m
ACCORDING THE QUESTION,
The area of rectangle is,
As we know that,
➟ Area = ( 3m + 6 ) ( 3m )
➟ 9m² + 12m
The area of rectangle is 9m² + 12m units.
Now, perimeter of rectangle is,
As we know that,
➟ Perimeter = 2 ( 3m + 6 + 3m )
➟ ( 2 ) ( 6m + 6 )
➟ 12m + 12
The perimeter of rectangle is 12m + 12 units.
