If a right isosceles triangle has an area of 192 cm, what is the height of the triangle?
xxMikexx [17]

The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.

Step-by-step explanation:

The given is,

               Area of right isosceles triangle is 192 square centimeters

Step:1

             Formula for area of  right isosceles triangle is,

                                       A=\frac{1}{2} a^{2}............................(1)

            Where, a - Sides of triangle

                         a = h = b

            Here, h - Height of triangle

                      b - Base of triangle

           From given,

                    Area, A = 192 square centimeters

           Equation (1) becomes.

                              192=\frac{1}{2} a^{2}

                                a^{2} = (2)(192)

                                     = 384

                                a^{2} = 384

          Take square root on both sides,

                                 a=\sqrt{384}

                                  a = 19.596 centimeters

         Height of right isosceles of triangle, a = h = 19.596 centimeters

Result:

        The height of the triangle is 19.596 centimeter, if a right isosceles triangle has an area of 192 square centimeters.
