Answer 1

Hey @neelimapankaj, Here is your answer⏬.

===============================================================

Answer:

7(2+√2 ) cm

Step-by-step explanation:

Let the other side of triangle is x cm

Then in isosceles right angle triangle two congruent sides are 7 cm

x² = (7)²+(7)²  

⇒x² = 49+49

⇒x²  = 198

⇒x = 7√2

Then perimeter of right angle isosceles triangle :

= 7+7+7√2  

= 14+7√2  

= 7(2+√2 )
