One side of the triangle is 7 cm, and the other is 2 times larger. Find the third side of the triangle if its perimeter is 32 cm

The perimeter of the shape is found by adding all the sides of the shape. One side of the triangle is 7 cm, and the other is twice as large:

7 * 2 = 14 cm – the second side of the triangle;

Find the third unknown side by subtracting two known sides from the perimeter:

32 – 7 – 14 = 32 – 21 = 11 cm – the third side of the triangle.

Answer: 11 cm
