The perimeter of a 2.5 scale factored version of this triangle would be C) 60.
In order to do this, we need to first multiply both of the known sides by 2.5
Leg 1 = 6 * 2.5 = 15
Leg 2 = 8 * 2.5 = 20
So our new legs are 15 and 20. We can find the hypotenuse by using the Pythagorean Theorem. Note that a and b would be the two legs and c would be the hypotenuse
a^2 + b^2 = c^2
15^2 + 20^2 = c^2
225 + 400 = c^2
625 = c^
25 = c
So now we have the sides of 15, 20 and 25. We add them all together to get the perimeter.
15 + 20 + 25 = 60
