Answer:

Ok ill help but please give me a lot of credit since i took the time to do it for you!

13 x 3 = 39, 39 x 2 = 78

9 x 3 = 27, 27 x 2 = 54

9 x 13 = 117, 117 x 2 = 234

234  + 78 + 54 = 366 mm

20 x 6 = 120, 120 x 2 = 240

4 x 20 = 80, 80 x 2 = 160

6 x 4 = 24, 24 x 2 = 48

240 + 160 + 48 = 448 cm

5 x 14 = 70, 70 x 2 = 140

5 x 16 = 80, 80 x 2 = 160

14 x 16 = 224 , 224  x 2 = 448

448 + 160 + 140 = 748 m

4 x 14 = 56, 56 x 2 = 112

17 x 4 = 68, 68 x 2 = 136

14 x 17 = 238, 238 x 2 = 476

476 + 112 + 136 = 724 ft

4 x 13 = 52, 52 x 2 = 104

13 x 19 = 247, 247 x 2 = 494

19 x 4 = 76, 76 x 2 = 152

104 + 494 + 152 = 750 in

14 x 9 = 126, 126 x 2 = 252

9 x 3 = 27, 27 x 2 = 54

3 x 14 = 42, 42 x 2 = 84

252 + 54 + 84 = 390 mm

7 x 12 = 84, 84 x 2 = 168

12 x 2 = 24, 24 x 2 = 48

2 x 7 = 14, 14 x 2 = 28

168 + 48 + 28 = 244 cm

6 x 4 = 24, 24 x 2 = 48

6 x 13 = 78, 78 x 2 = 156

4 x 13 = 52, 52 x 2 = 104

48 + 156 + 104 = 308 in

8 x 15 = 120, 120 x 2 = 240

4 x 15 = 60, 60 x 2 = 120

8 x 4 = 32, 32 x 2 = 64

240 + 120 + 64 = 424 ft

Please try to do 10 by yourself, thank you. Brainliest please.
