Area of a Isoceles Triangle
Height (h)=a2-b24
Perimeter (P)=2a+b
Area (A)=bh2

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=(2equal Side)+third Side

=(2a)+b

=(25)+6

=16


We know that,

Area=12baseheight

=12ba2-b24

=12652-624

=1264

=12
