Question

What is the perimeter of a triangle with sides 14mm and 17mm and the right angle is opposite the third side?

Answer 1

`=53mm`

Explanation:

So we have a right-angled triangle having `p=14`;`b=17` and we have to find `h=?`
`h=sqrt(p^2+b^2)`
or
`h=sqrt(14^2+17^2)`
`=sqrt(196+289)`
`=sqrt485`
`=22`
So the perimeter `=14+17+22`
`=53mm`
