The perimeter of an isosceles triangle is 15.6 centimeters and its base is 3 centimeters larger

The perimeter of an isosceles triangle is 15.6 centimeters and its base is 3 centimeters larger than the side. Find the sides of the triangle.

Given:
The triangle is isosceles.
The perimeter of this figure is 15.6 cm.
The base is 3 cm larger than the lateral side.

Let one side of the triangle be x cm.
Since the triangle is isosceles, the second side is x cm.
The base will be (x + 3) cm.
Let’s make the equation:
x + x + x + 3 = 15.6;
3x = 15.6 – 3;
3x = 12.6;
x = 12.6: 3;
x = 4.2.
Two sides 4.2 cm each.
Calculate the base of the triangle:
4.2 + 3 = 7.2 centimeters.
Answer: 4.2 cm; 4.2 cm; 7.2 cm.
