Explicación paso a paso:
1. perimetro = 9+9+9+9 = 36
area = 9^2 = 81
2. perimetro= 34
area = 14 x 3 = 42
3. perimetro= 10+10+12= 32
area= [8x12]/2= 48
4. perimetro= 7.5+7.5+7.5+7.5=30
area = 7.5^2= 56.25
5. perimetro= 8.2+8.2+3.5+3.5=23.4
area = 8.2 x 3.5 = 28.7
6. perimetro =10.5+10.13= 30.75
area = [10.5x8.5]/2 = 44.625
