The 6cm side is made up of a 2cm length and a 4cm length, 2+4 = 6.
The 5cm side is made up of a 2cm length and a 3cm length, 2+3 = 5.
Thank you for the quick reply, But how will I know this the next time I receive a similar figure? How does one know which figures to add together to get the answer like 5 and 6?
I did not know it was 5 and 6..I probably wouldn't of worked it out either, Which is why I don't understand how I will know in the future..
If you don't mind, Please explain..
