The length of one side of the triangle is 24 cm, this is 2 times the length of the second side and 5 cm less

The length of one side of the triangle is 24 cm, this is 2 times the length of the second side and 5 cm less than the length of the third side. Find the perimeter of the triangle.

First side – 24 cm

The second side is? cm 2 times less than 1

Third side – ? 5 cm more than 1

Perimeter -? cm

1) 24/2 – 12 (cm) – the second side;

2) 24 + 5 = 29 (cm) – third party;

The perimeter is the sum of the lengths of all sides:

3) 24 + 12 + 29 = 65 (cm) – perimeter.

Answer: 65 cm.
