Question

why we use
$\sqrt{2a \: }$
for finding perimeter explain please
​

Answer 1

because it uses 'B' form, and please make you question more clear because wdym by on perimeter of a plus a v to 4?

Answer 2

Answer:

Because we apply pythagoras theorem in the given triangle.

pythagoras theorem:

H^2= b^2+P^2

= 2a^2

H = √2×√a^2

H = √2a
