​

Answer 1

ANSWER ➜

Horon's formula state for a triangle with side of triangle ABC.

$a = \sqrt[]{s(s - a)(s - b)(s - c)}$

Whereas s=(a+b+c)/2

If u double side A.

$\sqrt{2s(2s - 2a)(2s - 2b)(2s - 2c)}$

$= 4a = \sqrt{s(s - a)(s - b)(s - c)}$

$= 4a$

The increase in area is 4A = A is equal to

3A The answer

=300

Hope it helps you

have a great day ☺️☺️
