To find the perimeter of a triangle, you simply add up the lengths of all three sides.
Here are the calculations for each triangle on the worksheet:
1. Top Left Triangle:
* Sides: 4 m, 7 m, 10 m
* Calculation: $4 + 7 + 10 = 21$
* Perimeter:
21 m
2. Top Right Triangle:
* Sides: 9 m, 5 m, 5 m
* Calculation: $9 + 5 + 5 = 19$
* Perimeter:
19 m
3. Middle Left Triangle:
* Sides: 6 ft, 3 ft, 3 ft
* Calculation: $6 + 3 + 3 = 12$
* Perimeter:
12 ft
4. Middle Right Triangle:
* Sides: 8.5 in, 8.5 in, 5 in
* Calculation: $8.5 + 8.5 + 5 = 22$
* Perimeter:
22 in
5. Bottom Left Triangle:
* Sides: 4.5 cm, 6.5 cm, 10.5 cm
* Calculation: $4.5 + 6.5 + 10.5 = 21.5$
* Perimeter:
21.5 cm
6. Bottom Right Triangle:
* Sides: 2.7 m, 2.7 m, 4.7 m
* Calculation: $2.7 + 2.7 + 4.7 = 10.1$
* Perimeter:
10.1 m
Final Answer:
Top Left: 21 m
Top Right: 19 m
Middle Left: 12 ft
Middle Right: 22 in
Bottom Left: 21.5 cm
Bottom Right: 10.1 m
