a) Perímetro= 26 b , b= 0,25 m
b) Perímetro= 9/2 b , b=1 m
c) Perímetro= 19 b , b= 0,5 m
d) Perímetro= 13 b , b= 0,73 m

Answer 1

Explicación paso a paso:

2(6b)

a=b/2

c=4a

total=9.5m

9.5=2(6b)+b+b/2+4(b/2)+(b+b/2+4(b/2))

9.5=12b+3b/2+4b/2+(3b/2+4b/2)

9.5=31b/2+7b/2

9.5=38b/2

2(9.5)=38b

19=38b

19/38=b+

0.5=b
