From this find out bhPerimeterArea of the isoceles triangles.

SolutionIsoceles Triangle FormulaArea Formula
 Area of Isoceles Triangle Height (h) = sqrt(a^2 - b^2/4)Perimeter (P) = 2 a + bArea (A) = (b h)/2Example : I know that for a isoceles triangles a = 5 and b = 6 . From this find out Area of the isoceles triangles."Here base " (b) = 6" and equal side " (a) = 5" (Given)""We know that,""Perimeter" = (2 * "equal Side") + "third Side" = (2 * a) + b = (2 * 5) + 6 = 16"We know that,""Area" = 1/2 * "base" * "height" = 1/2 * b * sqrt(a^2 - b^2/4) = 1/2 * 6 * sqrt(5^2 - 6^2/4) = 1/2 * 6 * 4  = 12
