Question

Find the perimeter of the right triangle.

Answer 1

b. 36

Explanation:

You have to use Pythagorean theorem. A squared + b squared = c squared.

a=12 12^2 (12 squared)= 144

b=9 9^2 (9 squared)= 81

144+81=225

Then you find the square root of 225 which is 15. Since you have the length for side c.

12+9+15=36

Answer 2

Step-by-step explanation

You would first have to find the hypotenuse to do that you would follow the formula c = √a²+b², giving you 15.

Next you would add all the sides P = a+b+c, giving you 36.

The perimeter of this triangle would be 36.
