Question

What is the perimeter of the triangle shown below?

Answer 1

I believe the answer is 30 units.

Answer 2

Here, Perpendicular = 5-(-7) = 5+7 = 12
Base = 5

Hypotenuse = √(B²+P²) = √(5²+12²) = √25+144 = √169 = 13

Now, Perimeter = H+B+P = 13+5+12 = 30 units

In short, Your answer would be Option C

Hope this helps!
