what is the sum of the lengths 39cm and 2m

2.39 metres or 239 cm

(the beauty of the metric system)

1 m = 100 cm

2 m = 200 cm

39 cm + 2 m = 39 + 200 = 239 cm

239 cm = 2.39 m

To find the sum of lengths in different units, we need to convert them to the same unit first. In this case, we have 39 cm and 2 m.

To convert cm to m, we divide by 100 because there are 100 centimeters in 1 meter. So, 39 cm becomes 39/100 = 0.39 m.

Now we have 0.39 m and 2 m as the lengths in the same unit (meters).

To find the sum, we simply add them: 0.39 m + 2 m = 2.39 m.

Therefore, the sum of 39 cm and 2 m is 2.39 m.
