Question

If the perimeter of an isosceles right triangle is (6+3√2)m then the area of the triangle is

Answer 1

Let, equal sides of the triangle=X
in triangle ABC
by Pythagorous theorem,
X•X+X•X=BC•BC
$2 {x}^{2} = bc$
$bc = \sqrt{2}x$
perimeter=6+3√2
2X+√2X=6+3√2
X(2+√2)=6+3√2
X=6+3√2/2+√2
X=3√2(√2+1)/√2(√2+1)
X=3m
BC=3√2

Answer 2

Step-by-step explanation:
