Question

A) a = 6,6 b = 4 h = 3

B) a = 10 b = 15 h = 7

C) a = 12 b = 6 h = 3

D) a = 7 b = 6 h = 4

E) a = 6 b = 4 h = 5

F) a = 6,5 b = 5,3 h = 2,8

Answer 1

 P=(a+b)*h /2

a)P=(6,6+4)*3 / 2

   P=31,8 /2

   P=15,9

b)

P=(10+15)*7 / 2

P=245/2

P=122,5

c)

P=(12+6)*3/2

P=54/2

P=27

d)

P=(7+6)*4/2

P=52/2

P=26

e)

P=(6+4)*5/2

P=50/2

P=25

f)

P=(6,5+5,3)*2,8 /2

P=33,04/2

P=16,52
