Question

Find the area of an isosceles right angled triangle whose each side containing the right angle is 8.4 cm.

Answer 1

An isosceles right angle triangle is like a square sheet of paper with sides of $8.4$ cm folded along the diagonal. The area of the isosceles right angle triangle is half that of the square which is $8.4\times 8.4=70.56$sq cm.

So the area of the isosceles right angle triangle is $=\frac{1}{2}\times 70.56=35.28$sq cm
