Explicación paso a paso:

b= 4    h= 11        

1) b x h/2 = 4 x 11 / 2 = 44 / 2 = 22

2) b  x h = 44

3) 2b + 2h = 8 + 22 = 30

b=4        h= ?             h= 12/b = 12/4 = 3  

1) b x h/2 = 4 x h/2 = 4h/2 = 2h =  2 x 3 = 6  o  b x h = 12  entonces b x h/2 seria 12/2 = 6

2) b x h = 12    

3) 2b + 2h = 2 x 4 + 2 h = 8 + 2h = 8 + 2 x 3 = 8 + 6 = 14

b= 15     h=6/5

1) b x h/2 = 15 x 6/5/2 = 90/5/2/1= 90/10 = 9

2) b x h = 15 x 6/5 = 90/5 = 18

3) 2b + 2h = 2 x  15 + 2 x 6/5 = 30 + 12/5 = 30/1 + 12/5 = 150 + 12/5 = 162/5 = 32,4
