what is the length of the diagonal line of this rectangle? width of 9cm, length of 16cm

(sqrt((16^2+9^2))

Have you tried drawing it?

You have 9cm and 16cm with a right angle between them.

The diagonal must make the hypotenuse of the right angled triange.

So How do you find the hypotenuse of a right angled triangle if you have the 2 other sides?

Can you figure it out?

Great anwer, helped me out too...

i ha ve no arms so i cant draw, i use ma face to type

That is okay - I think that is why you were born with a nose.
