The length of one side of the triangle is 24cm. This is 2 times longer than the length of the second side

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

We need to find the perimeter of the triangle. To do this, you need to know the formula:

P = a + b + c, where a, b, c are the sides of this triangle.

We know from the condition that the first side of the triangle is 24 cm.

The second side is 2 times smaller than the first, which means:

24: 2 = 12 cm.

The second side is 12 cm.

The third side is 5 cm larger than the first, which means:

24 + 5 = 29 cm.

Now that we know all the sides of the triangle, we can find its perimeter:

P = a + b + c = 24 + 12 + 29 = 65 cm.

Answer: The perimeter of the triangle is 65 cm.
