Question

the length of its side is 6 cm and the second side is twice the third side if the perimeter of the triangle is 18 cm find the sides of the triangle​

Answer 1

Answer:

Second side is 4 cm and third side is 8 cm

Explanation:

Length - 6 cm

Let 3rd side be - x

and

Second side be - 2x

Perimeter - 18 cm

Perimeter - sum of all sides

18 cm = x + 2x + 6 cm

18 cm = 3x + 6 cm

18 cm - 6 cm = 3x

12 cm = 3x

12 cm / 3 = x

4 cm = x
