In an isosceles right-angled triangle, the perimeter is 30 m. Find its area (Approximate)

38.63 m²

According to the question,

Perimeter of an isosceles triangle = 2x + y

Area of an isosceles right angle triangle = \(\frac{1}{2}\) × x²

x = equal sides of an isosceles triangle 

In an isosceles right angled triangle, the two sides on the right angle are equal

Let the equal sides = a
