1. Perimeter and area of Combined shapes

2. To find the perimeter of this L-shaped room
Think about
What else is needed?
6 m
5 m
3 m
2 m
3 m
Perimeter
= = 22m

3. To find the area of this L-shaped room
Think about
How can we do this?
7 m
5 m
3 m
2 m
4 m A B
Area of A
= 5 × 3
= 15 m2
Area of B
= 3 × 4
= 12 m2
Total area =
+ 12
= 27 m2 15

4. To find the area of this L-shaped room
Another way
7 m
5 m
3 m
2 m
4 m A B
Area of A
= 3 × 2
=6 m2
Area of B
= 7 x 3
= 21 m2
Total area =
+ 21
= 27 m2 6

5. Find the area of the shape
Solution:
The above shape can be splitted as Rectangle and triangle as shown below
