Question

an isoseles right angled triangle of which the length of each side of equal two sides is unit then find the perimeter of the triangle​

Answer 1

Step-by-step explanation:

In isosceles triangle two sides are equal,

So,

3x-1=2x+2

x=3

Perimeter=sum of all sides

=3x-1+2x+2+2x

=7x+1

Substituting value of x

Perimeter=7(3)+1

=21+1

=22

Thus x=3 and Perimeter of a triangle=22 square units

Answer 2

Answer:

perimeter will be x(2+√2).
