17) h=5
A= ½ (5) (6+9)
A= ½ (20)
A= 10

18) h=8
A= ½(8) (15 + 10)
= ½ (8) (25)
= ½ (200)
A= 100

19) h=10
A= ½ (10) (12+6)
A= ½ (180)
A= 90

20) 8+8=16
2+8=10
½(16)(10)
½(160)
A=80in^

21) ½(6)(6)
½ (36)
A= 18m^

22) 22) A = ½ (8) (6)
A= ½ (48)
A= 24ft^

23) A= ½ (20) (30)
A= ½ (600)
A= 300 ft^


24) A= ½ (10) (8)
A= ½ (80)
A= 40 in^

25) A= ½ (6) (5)
A= ½ (30)
A= 15 m^
