Answer 1

Answer:

Value of x = 3

third side = 6 units

perimeter of triangle = 22 units

Step-by-step explanation:

As given triangle is an isosceles

∴ two sides are equal.

∴ 3x - 1 = 2x + 2

∴ 3x - 2x = 2  + 1...… (taking likes terms together).

∴ x = 3

Now third side = 2x = 2×3 = 6 units.

Perimeter of triangle = sum of three sides

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

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

                                     = 7x + 1

                                     = (7×3) + 1

                                     = 21 + 1

                                     = 22 units
