One side of the triangle is 7 times smaller than the second and 66 cm smaller

One side of the triangle is 7 times smaller than the second and 66 cm smaller than the third. Find the sides of a triangle if its perimeter is 174 cm.

x cm – 1 side
7x cm – 2 side
x + 66 cm – 3 side
x + 7x + x + 66 = 174; 9x = 108; x = 12 cm – 1 side;
7 * 12 = 84 cm – 2 side
12 + 66 = 78 cm – 3rd side
