Answer: The length of both the other two side of the triangle​ are 11 sq. cm  

Step-by-step explanation:

Given : c² = 242

            a=b (isosceles Δ)

To find : a and b

Formula : a² + b² = c² (Pythagoras theorem)

a² + a² = 242 (a=b)

2a² = 242

a² = 121

a = √121

a = 11 sq. cm

b = 11 sq. cm (a=b)

Answer:

Length of each of the other two side of the triangle are 11 cm.

Step-by-step explanation:

Given:

Square of the length of hypotenuse = 242 cm.

Let length of each equal side of isosceles right angle triangle = x cm.

As we know that,

[tex]hypotenuse ^{2} =one side^{2} +other side^{2}[/tex]

  242 = [tex]x^{2}[/tex] +[tex]x^{2}[/tex]

 242 = 2[tex]x^{2}[/tex]

  [tex]x^{2}[/tex] = 242 /2

       = 121

   x=  [tex]\sqrt{121}[/tex] =11 cm.
