In an isosceles right-angled triangle, the perimeter is 30 m. Find its area (Approximate)
Answer & explanation
Correct answer: option 1
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
