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.
