The length of one leg of an isosceles right triangle is 3 ft . what is the perimeter of the triangle

Perimeter = 6+  ft

Step-by-step explanation:

Since given triangle is isosceles and right therefore two equals sides are the legs of right triangle given 3 and third side Hypotenuse say (x )  

Using Pythagorean theorem , we get  

taking square root both sides ,we get  

Three sides of given triangles are  

3 ft ,3ft and  

Perimeter is given by =   sum of  all three sides = 3+3+

                                                                              = 6 +   ft

answer: answer is b.

[m < b = 120º]
