10. 2,25 x 2 = 4,5 m
4,5 – 1,5 = 3 m
4,5 – 3 = 1,5 = 1½ m C.
11. Q = 3/7 x 49 = 21 B.
12. Buah = 2/1 x 35= 70
Bunga = 3/1 x 35 = 105
total = 175 pot C.
13. 8500 cm + 280 dm – 5 dam
( 8500 : 100) + ( 280 : 10) – ( 5 x 10)
85 + 28 – 50
63 m D
14. 74 kg = 0,74 kw
560 hg = 0.56 kw
200000 g = 2 kw
0,74 + 0,56 + 2 = 3,3 kw
15. –
16. –
17. L = p x l
= 32 x 15
= 480 cm²
L = ½ x a x t
= ½ x 16 x 7,5
= 60 cm²
480 – 60 = 420 cm² C.
