Question

From a rope of 2 dam 34 CM long 900 CM cut off. What is the length of the rope now

Answer 1

Answer:

1.134 dam

Step-by-step explanation:

Length of rope in cm = 2034cm

Length that was cut = 900cm

The length now in cm = 1134cm

The length now in dam = 1.134 dam

Answer 2

rope's initial length;

$l_{o} = 2 \: da \: m \: + 34 \: cm \\ = 2 \times 10 \: m \: + 34 \: cm \: \: \: \: \: \: \: \: ...(1 \: da \: m \: = 10 \: m) \\ = 20 \times 100 + 34 \: cm \: \: \: \: \: \: \: \: \: \: \: \: \: ...(1 \: m = 100 \: cm) \\ = 2034 \: cm$

rope's new length;

$l_{n} = l_{o} \: - 900 \: cm \\ = 2034 - 900 \: cm \\ = 1134 \: cm \: = \frac{1134}{100} \: m = 11.34 \: m = 1.134 \: da \: m \: \: \: \: \: ...(1 \: cm = \frac{1}{100} m)(1 \: m = \frac{1}{10} \: da \: m)$

Hence, the rope's new length is 11.34 m, or 1.134 da m
