so what you need to do here to check your work is to find 14 and 20 squared (which are 196 and 400) now your equation is 196 + 400 = c^2. now, you combine the like terms to make 596 = c^2. all you have to do now is find the square root of 596 (which is 24.4 when rounded to the nearest tenth). so yes, you are correct.
