Question

the perimeter of a right angeled isoceles triangle is 2+√2.find the area​

Answer 1

Answer:

1/2 unit^2

Step-by-step explanation:

if u take an isosceles right angle trian

gle

the two side have same length

let it be x unit

and other than these two the third side or hypotenuse will have x√2 unit

therefore perimeter =2x +x√2

2+√2=2x+x√2

=> x =1

as if the value of x is greater or lesser than 1 then we couldn't get the perimeter 2+√2

therefore area =1/2* b*h

=1/2*1*1

=1/2 unit^2
