Area and Perimeter of Composite Shapes. This can be done the same way we found the area of other polygons: Divide the shape into shapes you know how to work with. 3. 2. 6. 4. 10. I can find the area by breaking apart the shape two different ways. 3. 2. 6. 4. 10.

3 2 6 4 10
I can find the area by breaking apart the shape two different ways 3 2 6 4 10
I can find the area by breaking apart the shape two different ways 3 2 Area = 6 un² 6 4 Area = 40 un² 10 Total area of the shape is the area of the two combined: 46 units squared
When I do it this way, I am missing a value. But I can find it……. 3 2 6 4 10
Let’s Do Another One Together Find the perimeter and the area: 3 4 8 3 Perimeter = Area = 2 3 Notice that we are missing some side lengths
Find the area and perimeter Perimeter = Area =
A little harder? 7 4 5 3 5 4 Perimeter = Area =
Another 5 8 8 7 3 7 7 Perimeter = Area =
One More Together 13 5 12 2 2 4 Perimeter = Area =
On Your Own? 9 6 8 9 4 Perimeter = Area =
Closure: With a partner find the perimeter and area 5 3 6 4 2 1 5 6 5 6 6 Perimeter = Area =
