Question

Find the perimeter of a triangle with sides 12 inches, 9 inches, and 15 inches.

Answer 1

Hi there! P=L+W+H. It really doesn't matter what the length, width, and height is when your dealing with perimeter. In this case, the length is 12 inches, the width is 9 inches and the height is 15 inches. 12 inches+9inches+15inches=36 inches. Therefore, the answer is 36 inches.

Answer 2

If its perimeter, it should be quite easy to find. Just add 12+9+15. Which equals 36. So the perimeter is 36 inches. -Hope it helps!
