Answer 1

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
