Answer:
The order of the answers provided are in the order of the photos uploaded in the question :)
Explanation:
To find the perimeter we have to add the lengths of all the sides together
To find the area we have to subtract the area of the gaps by the area of the whole shape if it were to be a rectangle or square
1)
- Perimeter: 4 + 2 + 2 + 4 + 2 + 6 = 20 m
- Area: (4 x 6) - (4 x 2) = 16 m²
2)
- Perimeter: 4 + 2 + 4 + 3 + 6 + 1 = 20 cm
- Area: (4 x 6) - (1 x 4) = 20 cm²
3)
- Perimeter: 8 + 6 + 2 + 2 + 6 + 8 = 32 m
- Area: (8 x 8) - (2 x 2) = 60 m²
4)
- Perimeter: 5 + 5 + 3 + 1 + 2 + 6 = 22 cm
- Area: (6 x 5) - (3 x 1) = 27 cm²
5)
- Perimeter: 6 + 2 + 3 + 3 + 2 + 3 + 1 + 2 = 22 km
- Area: (6 x 5) - (3 x 1) - (3 x 3) = 18 km²
Hope this helps, have a great day!!
