Answer 1

Answer:

Isosceles triangle has two sides equal ,that means there should be only two values

Step-by-step explanation:

If it was a typing mistake (scalene triangle)

Here are steps :

Perimeter of scalene triangle= a+b+c

P=(3x-1)+(2x+2)+2x

.°. P=3x-1+2x+2+2x

P=7x-1+2

P=7x+1

7x=1

.°.x=⅐

Answer 2

Answer:

22units

Step-by-step explanation:

since 2 sides of isoseles traingle are equal & it is given 3x-1&2x+2

=》 3x–1 = 2x+2

=》 3x-2x = 1+2 =》 X = 3 unit

=》1st side = 3x-1 = 3×3 - 1 = 8 unit

=》 2nd side = 2x + 2 = 8 unit

=》 3rd side = 2x = 2×3 = 6 unit

=》● PERIMETER OF TRAINGLE = sum of all side

= 8+8+6 = 22units
