Area of Isoceles Triangle
Height
`(h) = sqrt(a^2  b^2/4)`
Perimeter
`(P) = 2 a + b`
Area
`(A) = (b h)/2`
Example :
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`
