Answer:
∴ Perimeter = sum of all sides
figure 1.
Perimeter = 15 + 7 + 15 + 7
Perimeter = 44 cm
figure 2.
Perimeter = 8 + 8 + 10
Perimeter = 26 cm
figure 3.
Perimeter = 8 + 8 + 8 + 8
Perimeter = 32 cm
figure 4.
Perimeter = 17 + 17 + 32
Perimeter = 57 cm
figure 5.
Perimeter = 24+ 9 + 9 + 27
Perimeter = 69 cm
Hope this helps...
