Question

What is the perimeter of a 5 by 12 triangle?

Answer 1

The perimeter of the triangle is 30 units.

Explanation:

So

`x^2`=
`5^2\\`+
`12^2`

`x^2`= 25+144

`x^2`=169

`x^2\\`=
`\sqrt 169`

`x`=13

The greatest side / hypotenuse of the triangle = 13

The perimeter of a triangle = Sum of all sides

5+12+13

30 units
