Add lengths given in centimetres and metres

To add lengths measured in metres and centimetres, you need to first convert the metres to centimetres. This is because metres and centimetres are different units of measurement for length, and you cannot directly add them without first converting them to the same unit. Here's how to do it:

Convert metres to centimetres: As there are 100 centimetres in a metre, you need to multiply the number of metres by 100 to convert it to centimetres.

For example, let's say you are asked to add 2 metres and 35 centimetres. To convert the 2 metres to centimetres, you would multiply by 100:

2 metres x 100 = 200 centimetres

Now that you have the metre length in centimetres, you can add it to the other length which is already in centimetres.

In our example, we converted 2 metres to 200 centimetres, and we also have 35 centimetres. To add them together:

200 centimetres + 35 centimetres = 235 centimetres

So, the combined length of 2 metres and 35 centimetres is 235 centimetres.

Another example, add 0.9 metres and 74 centimetres.

Converting the metres to centimetres we have 0.9 m x 100 = 90 cm.

Adding the centimetres we have 90 cm + 74 cm = 164 cm.

So, the combined length of 0.9 metres and 74 centimetres is 164 centimetres.

This topic asks you to add lengths in metres and centimetres together by first converting the metres to centimetres. Your answers should be in centimetres.
