Jolene is putting trim around the edge of a triangle head scarf. The scarf from a right triangle with legs that measures 15 inches each. Find how much trim Jolene needs to the nearest tenth of an inch

Since it's a right triangle, you can use Pythagorean theorem to find the hypotenuse. a^2 + b^2 = c^2

So it would be 15^2 + 15^2 = c^2

225+225=c^2 / 450=c

21.21=c

Now just find the perimeter and you'll get the answer to your question above.
