Question

how to do this get b option got stuck

Answer 1

Answer:

correct option is A

Step-by-step explanation:

In an isosceles triangle, the height- line divides the triangle into two equal areas and the base into two equal halves.

Given base =a

each equal side =b.

Using Pythagoras Theorem, we get

Therefore, height =b2−(2a)2=44b2−a2

Therefore, area of the triangle =21×base×height

=21×a×44b2−a2

=4a4b2−a2

Hence, option A.
