Question

The equal sides of isosceles triangle are (2x+3) cm and (4x-1) cm. if the third side is (3x-2) cm, then find the value of x and the perimeter of the triangle.​

Answer 1

Answer:

x=2 cm; Perimeter=18 cm

Step-by-step explanation:

Equal sides of the triangle = (2x+3) cm and (4x-1) cm

Hence, (2x+3)=(4x-1)

or, 2x-4x=-1-3

or, -2x=-4

or, x=(-4)÷(-2)

or, x=2 cm

Therefore, x=2

Perimeter= Sum of all the sides

=(2x+3)+(4x-1)+(3x-2)

=(4+3)+(8-1)+(6-2)

=7+7+4=18 cm
