Question

Two equal sides of an isosceles triangle are (3x - 1) units and (2x + 2) units. The third side is 2x units. Find x and
the perimeter of the triangle.

Answer 1

Answer: x=3 units. Perimeter:22 units

Step-by-step explanation:

P=perimeter

3x-1=2x+2

x-1=2

x=3 units

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

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

P=9-1+6+2+6

P=8+8+6

P=22 units
