1: If both A and B are irrational numbers and A+B=3, the values of A and B can be __3- root 3 and root 3____. (only fill in one group).

2. The ratio of waist length to base length of an isosceles triangle is 5: 8, and the height of its base is three times that of the root number 3, so the circumference of this isosceles triangle is __ 18 times the root number 3 _ _ _, and the area is _ 36 _ _.

The height of the bottom edge is three times that of the root number 3, so the waist length is five times that of the root number 3 and the bottom edge is eight times that of the root number 3.

The circumference is equal to 18 times the root number 3.

The area is equal to 36
