This cannot be done as the square root are 2 identical numbers that, when multiplied, equal the original number. A triangle is not a number, therefore, this is question is not rightly asked.

If two sides are given and you need to know the length of the third side use the Pythagrean Theorem formula. Then you find the square root. c² = a² + b²* * * * *That is useful only if the triangle is a right angled triangle. Most are not. The correct answer depends on what information you do have.
If it's a right triangle, a2 + b2 = c2 3 + 5 = c2 c = the square root of 8.
1) The hypotenuse side will ALWAYS be the the side w/ the radical 2. 2) So if you want to find the HYPOTENUSE of an ISOSCELES triangle, you MULTIPLY one of the LEGS by the the square root of 2. 3) If you want to find the LEG of an ISOSCELES triangle, you DIVIDE the HYPOTENUSE by the square root of 2. ***** Hypotenuse of an isosceles triangle= one leg divided by square root of 2. ***** Leg of an isosceles triangle= hypotenuse divided by the square root of 2.

The formula for the area of a square is A=s2. So to find the sidelength, find the square root of the area.
square the length of the 2 shorter sides, add them together, take the square root and you have the hypotenuse
