Question

The perimeter of an isosceles right angled triangle is 2p unit. The area of the same triangle is

Answer 1

Since the triangle is isosceles right, the sides are a,a and √2 a units.

Now perimeter is a+a+√2a = (2+√2)a (=2p)

So, a = 2p/(2+√2)

Now area = 1/2 * a * a

                = 1/2 * (2p/(2+√2))²

               = 2p²/(2+√2)²

               = p²/(1+√2)²

               = p²/(2√2 + 3) square unit

Answer 2

Answer:

AC² = AB² + BC²

AC² = X² + X²

AC² = 2x²

AC² = √2x²

AC² = x√2
